WATER RESOURCES OF THE RIO GRANDE BASIN, 1888- 
1913, INCLUDING SURFACE WATER SUPPLY OF THE 
WESTERN GULF OF MEXICO BASINS, 1913. 



By Robert Follansbee and H. J. Dean. 



SCOPE OF REPORT. 

This volume, which is one of a series of 12 reports presenting results 
of measurements of flow made on streams in the United States during 
the year 1913, includes all data concerning the Rio Grande and its 
tributaries collected prior to September 30 of that year. 

Systematic study of run-off in the Rio Grande basin was begun by 
the Federal Government near Embudo, N. Mex., soon after the 
passage of the act of October 2, 1888, which authorized the organiza- 
tion of the irrigation survey under the direction of the United States 
Geological Survey. A camp of instruction for hydrographers was 
estabhshed near Embudo, and at this camp and the gaging station 
near by, the methods of stream measurements now in general use were 
systematized. In the spring of 1889 additional stations were estab- 
lished on the Rio Grande near Del Norte, Colo., and El Paso, Tex. 
From this beginning the work of measuring the waters of the Rio 
Grande basin has been expanded not only by the Geological Survey 
acting alone but by the Survey in cooperation with the American 
section of the International Water Commission ^ and the State 
engineers of Colorado and New Mexico. At the end of September, 
1913, records had been obtained at 93 gaging stations. 

The present report contains not only all data concerning stream 
flow in the Rio Grande basin collected by the Survey and cooperating 
parties but also records furnished by individuals connected with 
private interests. Most of the records here assembled have been 
taken from the publications of the Geological Survey, but original 
estimates have been revised where later data have indicated errors. 
The most notable necessity for revisions was in the older estimates 
of winter flow of the Rio Grande at Del Norte and Lobatos, the fig- 
ures given in the present report being considerably lower than those 
first published. Tables of daily discharge not heretofore pubhshed 
have been supplied from the original computations.

10 WATER RESOURCES OF RIO GRANDE BASIN, 1888-1913. 

The drainage area is stated in connection with the run-off data for 
only a few of the stations, and no estimates of run-off per square mile 
have been made, for the maps for the greater part of the basin are so 
poor and the unit run-off for different areas varies between limits so 
wide that such estimates would be of little value. 

The results of studies of precipitation, evaporation, and sedimen- 
tation as factors in determining the value of reservoir sites for storage 
of flood waters, on which future development must largely depend, 
are also presented in this report. 

COOPERATION AND ASSISTANCE. 

The American section of the International Water Commission 
began the work of stream gaging in 1897, by taking over the station 
at El Paso, Tex., formerly maintained by the Geological Survey. In 
1900 a number of stations on the lower Rio Grande and tributaries 
below El Paso were estabhshed by the American and Mexican sections 
of the Commission, and in 1901 the station on the Rio Grande at San 
Marcial was taken over from the Geological Survey. These stations 
have been maintained to the present time under the immediate 
direction of W. W. FoUett, United States consulting engineer, through 
whom the chairman of the commission has furnished the records and 
to whom special acknowledgments are due. 

A large part of the field data for the Pecos River basin was furnished 
by the United States Reclamation Service, by whom the stations were 
maintained. 

Since 1909 the State engineer of Colorado has cooperated in the 
maintenance of the stations in Colorado and for 1912 and 1913 he has 
furnished all field data. 

From 1907 to 1912 the work in New Mexico was carried on under 
the immediate supervision of the Territorial engineer. During the 
later part of 1912 a cooperative agreement was made with the State 
engineer and an office of the Geological Survey was established at 
Santa Fe in connection with the State engineer's office. 

Acknowledgments are due also to the State engineers of Colorado 
and New Mexico for cooperation in making a complete seepage inves- 
tigation of the Rio Grande from Del Norte, Colo., to El Paso, Tex., for 
use in this report. 

The United States Forest Service has prepared the data used in 
compiling the statements regarding forestation in the drainage basin. 

Mr. W. L. Rockwell, irrigation engineer, Department of Agriculture, 
furnished the records of evaporation at the United States Experiment 
farm near San Antonio, Texas. 

Mr. R. H. Forbes, director of the Agricultural Experiment Station 
at Tucson, Ariz., furnished the records of evaporation near Phoenix, 
Ariz. 



BIBLIOGEAPHY. 11 

Acknowledgments are also due to a number of corporations and 
indi\dduals for furnishing records, as noted in connection with each 
station affected. 

The writers have assembled and reviewed the stream-flow data here 
presented and have made such changes in previously published 
figures as were necessary to reconcile apparent discrepancies. They 
have also reviewed and discussed the results of investigations of pre- 
cipitation, seepage, evaporation, and sedimentation.

DEFINITION OF TERMS. 

The volume of water flowing in a stream — the "run-off" or "dis- 
charge" — is expressed in various terms, each of which has become 
associated with a certain class of work. These terms may be divided 
into two groups — (1) those which represent a rate of flow, as second- 
feet, gallons per minute, miner's inches, and run-off in second-feet 
per square mile, and (2) those which represent the actual quantity 
of water, as run-off in depth in inches, and acre-feet. The units 
used in this series of reports are second-feet, second-feet per square 
mile, run-off in depth in inches, and acre-feet. They may be defined 
as follows : 

"Second-foot" is an abbreviation for cubic foot per second and 
is the unit for the rate of discharge of water flowing in a stream 1 
foot wide, 1 foot deep, at a rate of 1 foot per second. It is generally 
used as a fundamental unit from which others are computed by the 
use of the factors given in the accompanying table of equivalents. 

"Second-feet per square mile" is the average number of cubic 
feet of water flowing per second from each square mile of area drained, 
on the assumption that the run-off is distributed uniformly both as 
regards time and area. 

"Run-off (depth in inches)" is the depth to which the drainage 
area would be covered if all the water flowing from it in a given 
period were conserved and uniformly distributed on the surface. 
It is used for comparing run-off with rainfall, which is usually 
expressed in depth in inches. 

An "acre-foot" is equivalent to 43,560 cubic feet and is the quan- 
tity required to cover an acre to the depth of 1 foot. The term is 
commonly used in connection with storage for irrigation.

EXPLANATION OF DATA. 

The data presented in this report cover the years beginning 
October 1 and ending September 30, and not, as in previous reports, 
the calendar years. At the first of January in most parts of the 
country a large amount of precipitation for the preceding three 
months is stored, either as ground water in the form of snow, or in 
lakes. This stored water passes off in the streams during the spring 
break-up. At the end of September the only stored water available 
for run-off in the streams is possibly a small amount held in ground 
storage. Therefore, the run-off for a year, beginning with October 1, 
is practically all derived from precipitation occurring within that 
year. 

The use of this climatic year in studies of stream flow is applicable 
only to work in the Temperate Zone, as south of about the twenty- 
eighth parallel of latitude precipitation is greatest during the sum- 
mer months. The effect of the rainy season in Mexico is shown in 
the run-off data for all stations on the Rio Grande below El Paso, Tex. 

For each regular current-meter gaging station the following data, 
so far as available, are given: Description of the station, list of dis- 
charge measurements, table of daily gage heights, table of daily dis- 
charge, table of monthly and yearly discharge and run-off. For sta- 
tions located at weirs or dams the gage-height table is usually omitted 

In addition to statements regarding the location and installation of 
current-meter stations the descriptions give information in regard to 



16 WATER EESOUECES OP EIO GEANDE BASIN, 1888-1913. 

any conditions that may affect the constancy of the relation of gage 
height to discharge, covering such points as ice, logging, shifting chan- 
nels, and backwater; also information regarding diversions which 
decrease the total flow at the measuring section. Statements are also 
made regarding the accuracy of the data. 

The table of daily gage heights records the daily fluctuations of the 
surface of the river as found from the mean of the gage readings taken 
each day, usually in the morning and in the evening. The gage 
height given in the table represents the elevation of the surface of the 
water above the zero of the gage. All gage heights affected by the 
presence of ice in the streams or by backwater from obstructions are 
pubhshed as recorded, with suitable footnotes. The rating table is 
not apphcable for such periods unless the proper corrections to the 
gage heights are known and applied. Attention is called to the fact 
that the zero of the gage is placed at an arbitrary datum and has no 
relation to zero flow or the bottom of the river. In general the zero 
is located somewhat below the lowest known flow, so that readings 
of negative values shall not occur. 

The discharge measurements and gage heights are the base data 
from which rating tables, daily discharge tables, and monthly dis- 
charge tables are computed. 

The rating tables gives, either directly or by interpolation, the dis- 
charge in second-feet corresponding to every stage of the river recorded 
during the period for which it is applicable. It is not published in 
this report, but can be determined from the tables of daily gage heights 
and daily discharge as follows : 

First plot the discharge measurements for the current and earlier 
years on cross-section paper, with gage heights in feet as ordinates 
and dicharge in second-feet as abscissas. Then tabulate a number 
of gage heights taken from the daily gage-height table for the com- 
plete range of stage given and the corresponding discharges for the 
days selected from the daily discharge table and plot the values on 
cross-section paper. The last points plotted wiU define the rating 
curve used and will He among the plotted discharge measurements. 
After drawing the rating curve a table can be developed by scaling 
off the discharge in second-feet for each tenth foot of gage height. 
These values should be so adjusted that the first difference shall 
always be increasing or constant except for known backwater periods. 

The table of daily discharge gives the discharge in second-feet 
corresponding to the observed gage heights as determined from the 
rating tables. 

In the table of monthly discharge, the colunm headed "Maximum" 
gives the mean flow, as determined from the rating table, for the day 
when the mean gage height was highest. As the gage height is the

mean for the clay, it does not indicate correctly the stage when the 
water surface was at crest height, and the corresponding discharge 
was consequently larger than given in the maximum column. Like- 
^vise in the column of ''Minimum" the quantity given is the mean 
flow for the day when the mean gage height was lowest. The column 
headed ''Mean" is the average flow in cubic feet for each second dur- 
ing the month. On this the computations for the remaining columns, 
which are defined on page 12, are based. 

The field methods used in the collection of the data presented in 
this series of reports are described in the introductory sections of 
United States Geological Survey Water-Supply Papers 261 to 272, 
inclusive, "Surface water supply of the United States, 1909." 

Plate I shows typical gaging stations. Plate II shows current 
meters used in the work. 

ACCURACY OF FIELD DATA AND COMPUTED RESULTS. 

The accuracy of stream-flow data depends (1) on the permanence of 
channel and of the relation between discharge and stage, and (2) on 
the accuracy of observation of stage measurements of discharge, and 
interpretation of data. 

In order to give engineers and others information regarding the 
probable accuracy of the computed results, footnotes are added to the 
daily discharge tables, stating the probable accuracy of the rating 
cin-ves used, and an accuracy column is inserted in the monthly dis- 
charge table. For the rating curves "well defined" indicates, in gen- 
eral, that the rating is probably accurate within 5 per cent; "fairly 
well defined," within 10 per cent; "poorly defined" or "approxi- 
mate," within 15 to 25 per cent. These notes are very general and 
pre based on the plotting of the individual measurements with refer- 
ence to the mean rating curve. 

The accuracy column in the monthly discharge table does not 
apply to the maximum or minimum nor to any individual day, but to 
the montlily mean. It is based on the accuracy of the rating, the 
probable reliability of the observer, and knowledge of local conditions. 
In this column A indicates that the mean monthly flow is probably 
accurate within 5 per cent; B, within 10 per cent; C, within 15 per 
cent; D, within 25 per cent. Special conditions are covered by foot- 
notes. 

In general the base data collected each year by the Survey engineers 
are published not only to comply with the law but to aflord any 
engineer the means of examining and adjusting to his own needs the 
results of the computations. The table of montlily discharge is so 
arranged as to give only a general idea of the flow at the station and 
should not be used for other than preliminary estimates. The deter-

minations of daily discharge allow more detailed studies of the varia- 
tion in flow by which the period of deficiency may be determined. 

It should be borne in mind that the observations in each succeeding 
year may be expected to throw new light on data already collected 
and published. 

GENERAL FEATURES OF THE RIO GRANDE DRAINAGE 

BASIN. 

LOCATION AND BOUNDARIES. 

The area nominally belonging to the Rio Grande basin comprises 
the San Luis Valley and the region westward to the Continental 
Divide in Colorado, the greater part of New Mexico (except the 
western fifth of the State, and an area in the northeast corner approxi- 
mately 140 miles square), the western panhandle region in Texas, 
and a comparatively narrow strip along the lower river; in Mexico 
it comprises the greater part of the State of Chihuahua, large parts 
of Coahuila and Nuevo Leon, and small parts of Durango and 
Tamauhpas. (See PL III.) 

In Colorado the boundaries of the basin are clearly marked by the 
almost continuous ring of mountains separating it from the Arkansas 
basin on the east and the Colorado basin on the north and west. 

In New Mexico the boundaries are much less sharply defined, 
especially on the western border which reaches the high plateaus or 
mesas that characterize the greater part of the western section of 
the State and that commonly are either without surface drainage 
channels or form closed basins draining toward the center. In 
general, however, the western boundary may be said to coincide with 
the Cejita Blanca Range, Chacre Mesa, Zuni Mountains, and the 
west end of the Datil and Black ranges. From the northeast corner 
of Grant County the boundary line runs southwest to Bear Mountain, 
whence it takes a southerly direction to the Mexican Hne. The east- 
ern boundary in New Mexico is more clearly marked. As far south 
as Las Vegas it consists of the extension of the Sangre de Cristo 
Range; southeastward from Las Vegas it is well defined by the divides 
between the fines of natural drainage, until it reaches the high plateau 
region in Roosevelt County, where it again becomes indefinite, as 
this region of high plains is devoid of surface drainage fines. Beyond 
the region of high plateaus, which does not extend east of the one 
hundred and second meridian, the boundary is fairly well defined to 
the Gulf, lying paraUel to the Pecos at a distance of about 50 miles to 
the east, and below the mouth of the Pecos roughly paralleling the Rio 
Grande at an average distance of 30 miles. 

In Mexico the boundary of the nominal drainage area coincides 
with the mountain ranges in the western part of the State of Chi-

hiiahua. It turns eastward in the northern part of the State of 
Durango and takes a generally easterly course to the Gulf at the 
mouth of the Rio Grantle. As in the United States, however, the 
effective drainage area of the river is considerably reduced by the 
large nonproducmg areas. 

TOPOGRAPHY. 

The topographic features of the area drained by the Rio Grande 
range in variety from mountain peaks 14,000 feet and more in eleva- 
tion to the low plains bordering the Gulf. The most important area 
as regards water supply is the mountainous part of the Colorado 
section above San Luis Valley, where the Rio Grande and its tribu- 
taries flow through narrow valleys whose sides extend up to the 
crest of the Continental Divide. San Luis Valley is a high level 
plateau at an elevation ranging from 7,500 to 8,000 feet. 

The New Mexico section of the basin is a high plateau region 
traversed from north to south by more or less parallel mountain 
ranges that form long, narrow vaUeys, some of which are completely 
inclosed. In this area elevations range from 13,000 feet in the moun- 
tains near Santa Fe to less than 4,000 feet in the valleys of the Rio 
Grande and Pecos. 

Below El Paso, in the trans-Pecos region of Texas, there is a 
mountainous area that probably extends into the Mexican part of 
the basin and that, in Texas, attains altitudes of 7,000 to 8,000 feet. 
East and south of the trans-Pecos region the country gradually 
becomes smoother, passing from the liigh-plateau region to the 
Coastal Plain by crossing the fall hne below the mouth of the Pecos. 
The Coastal Plain is characteristically a region of comparatively low 
rehef, but its surface is broken by occasional undulations and hills 
of considerable height. 

CLOSED BASINS. 

As the Rio Grande as far south as El Paso and beyond traverses 
the high plateau or intermountain region, the drainage boundaries 
include many areas from which neither the river nor its tributaries 
receive any surface run-off. 

SAN LUIS VALLEY. 

The nonproducing area nearest the headwaters is found in San 
Luis Valley, in Colorado, north of the Rio Grande. The drainage 
from the entire northern portion of the valley flows into a group of 
lakes, of which the San Luis is the largest. As these lakes have no 
surface outlet, the water is lost by evaporation or possibly in part 
by seepage. "The old overflow drainage course to the Rio Grande 
still exists, but it has been so blocked and concealed by incipient 



20 WATEE EESOTJRCES OF KIO GEANDE BASIN, 1888-1913. 

sand dunes as to be very difficult to trace, except in its general fea- 
tures."^ The drainage area included in this nonproductive basin is 
approximately 2,700 square miles. 

BASINS BETWEEN RIO GRANDE VALLEY AND PECOS BASIN. 

Beginning about 25 miles south of Santa Fe and extending as far 
south as El Paso, there is a wide strip of country stretching from 
within a few miles of the Rio Grande valley eastward to the Guadalupe, 
Sacramento, and Jicarilla mountains and the Sierra Blanca. This 
area is divided lengthwise by the Organ and San Andreas mountains, 
the Sierra Oscura, and the Chupadera Mesa into two distinct basins, 
each draining toward the center and having no outlet for surface 
drainage. The western division comprises the Jornada del Muerto 
("journey of death," so called by the earliest travelers from its desert 
wastes), which is separated from the Rio Grande valley by the 
mountain ranges paralleling it. Within this area, which is an almost 
level plain, surface waters from the mountains drain toward the 
center but sink into the porous soil before reaching very far out on 
the plain. There are no cross-drainage channels. 

The eastern division includes at the north Estancia Valley a closed 
depression comprising an area of approximately 2,000 square miles, 
without perennial streams except tiny ones in the mountains that 
sink as soon as they reach the plain, and the Encino and Pinos Wells 
basins, lying east of Estancia Valley. Owing to the relatively 
elevated position of this area it is possible that some of the ground 
water may find its way into the lower adjacent regions.^ South of 
Estancia Valley is the Tularosa Basin, 150 miles in maximum length, 
60 miles in maximum width, and containing approximately 6,000 
square miles.^ Southeast of the Tularosa Basin, and separated fronT 
it by the Hueco Mountains, is a large nonproducing area which 
stretches to the Guadalupe Mountains on the east and nearly to the 
Rio Grande in El Paso, Culberson, Jeff Davis, and northern Presidio 
counties in Texas, and which is another practically closed basin, 
draining toward a central area where the water is lost by absorption 
and evaporation.* 

The nonproducing area between the Rio Grande and Pecos valleys 
above El Paso comprises approximately 13,000 square miles.

GENERAL FEATURES OF RIO GRANDE BASIN. 21 

BASINS WEST OF RIO GRANDE. 

Across the Rio Grande from the Jornada is another closed basin, 
known as La Mesa, which extends from a point near Las Cruces 
southward into Mexico, sloping gently to the south. West of La 
Mesa is a closed basin several hundred square miles in area, which is 
drained by Mimbres River, an interior stream. Thus, it may be 
considered that the western boundary of the effective drainage area 
follows the Mimbres Range and then turns eastward, reaching nearly 
to the Rio Grande and paralling that stream within a few miles to 
the Mexican line. 

BASIN EAST OF PECOS RIVER IN NEW MEXICO. 

The Rio Grande basin in southeastern New Mexico comprises a part 
of the plateau area known as the High Plains and contributes no 
surface drainage to the river, for the rainfall is quickly evaporated or 
absorbed. The western edge of the High Plains area lies roughly 
parallel to the Pecos at a distance of 1 5 to 20 miles. The strip of area 
between the edge of the High Plains and the Pecos is almost devoid 
of drainage channels extending to the river, as the streams quickly 
lose themselves in the soil. Thus practically no surface run-off 
reaches the Pecos from the area lying to the east in Chaves and Eddy 
counties, N. Mex. Farther south, in Texas, the drainage lines are 
somewhat better developed, insuring the entrance into the Pecos of 
surface drainage from the eastern part of its basin. 

BASINS IN MEXICO. 

The region known as La Mesa in New Mexico extends southward 
into Mexico and merges with other nonproducing areas, cutting down 
the effective area from which surface run-off is secured to a compara- 
tively narrow strip along the western side of the Rio Grande from 
Juarez nearly to the mouth of the Rio Conchos. East of the com- 
paratively narrow area drained by Rio Conchos there is a large bolson 
or nonproducing area comprising many hundred square mUes in the 
southeastern part of Chihuahua, western part of Coahuda, and north- 
ern part of Durango. These two regions comprise approximately 
one-third of the nominal drainage area of the Rio Grande in Mexico, 

PRECIPITATION. 
PERIODS COVERED BY RECORDS. 

Relatively so few rainfall records of any considerable length are 
available for this section of the country that, in order to obtain a 
uniform basis for determining the distribution of rainfall throughout

the Rio Grande Basin, it was necessary to use the comparatively short 
period of 10 years, from 1903 to 1912, inclusive, but even this period 
was too long to include more than three or four stations in the Colo- 
rado portion of the area, so it has not been possible to show graphically 
the distribution in that section. 

The part of the basin in New Mexico is fairly well covered with 36 
10-year records and with sufficient records of greater length to 
enable comparison between the 10-year mean and the station mean 
for periods ranging from 30 to 54 years. The following table shows 
this comparison:

From this table it is seen that at no point does the mean for the 
10-year period differ from the station mean for 30 years or more by 
as much as 2 inches. 

The part of Texas drained by the Rio Grande is so sparcely settled 
that it has been impossible to obtain records covering the 10-year 
period from 1903 to 1912 at more than a dozen points within or 
bordering it. But as the distribution of rainfall is more uniform in 
Texas than in the upper part of the Rio Grande basin, these records 
are sufficient to show the distribution approximately. The following 
table shows the comparison between the 10-year mean and the 
station mean for the long-time records available :

GENERAL FEATURES OF RIO GRANDE BASIN. 23 

From this table it appears that the precipitation in the 10-year 
period ranged from 1.5 to 3.5 inches below the normal, except at 
Fort Mcintosh and El Paso, where it was slightly above. 

DISTRIBUTION. 

The records of precipitation in the Colorado part of the Rio Grande 
basin are few and for the most part scattering, especially at the 
higher altitudes. The longest record is that at San Luis (elevation 
7,794) in the eastern part of the San Luis Valley, and tliis is con- 
tinuous only since 1891. At Marshall Pass (elevation 10,856) there 
is an 8-year record; at Cumbres (elevation 10,015), a 5-year record; 
at Hermit (elevation 9,843), a 3-year record; and at Antelope Springs 
(elevation 8,902), a 3-year record. The remaining records are either 
at lower altitudes or are too meager to be of much value. 

The existing data show the mean annual precipitation to be heaviest 
on the Conejos Mountains on the western boundary. The annual 
precipitation at Platoro (elevation 10,015) is upward of 22 inches, 
and at Cumbres (elevation 10,800) observations in 1877 and 1878 
showed a mean precipitation of 36 inches. In the upper part of the 
basin, although the altitudes are nearly as great, the precipitation 
is somewhat less, as shown by a mean of 16 inches for 2 years at 
Hermit (elevation 9,843) and a mean of 16 inches for 8 years at 
Marshall Pass (elevation 10,856). The gi-eater precipitation in 
the Conejos Mountains is probably due to the fact that to the west 
there are no large mountain masses to induce precipitation before 
reaching the Conejos Range, as in the case of the mountains bounding 
the headwater streams. 

The precipitation rapidly decreases with the altitude, falhng from 
the values just given to a mean ranging from 7 to 9 inches in the 
San Luis Valley, where tlie elevation ranges between 7,500 and 8,000 
feet. The influence of the Sangre de Cristo Range, located on the 
eastern border of the area, in inducing rainfall, especially during the 
prevaiUng periods of easterly winds, is seen by the increased pre- 
cipitation as these mountains are approached. At Blanca (eleva- 
tion 7,865) the mean for 3 years is nearly 10 inches, and at San Luis 
(elevation 7,794) the mean for 22 years is 11.6 inches. Two years' 
record at La Veta Pass (approximate elevation 9,500) gives a mean 
precipitation of about 20 inches. 

To show grapliically the mean annual distribution of rainfall 
throughout the New Mexico and Texas portions of the basin, lines 
of equal rainfall for variations of 2 inches have been drawn on the 
map (PI. III). Altitude has such a marked influence on precipi- 
tation, especially in the upper parts of the basin, that it was neces- 
sary to take this into account so far as possible in showing the approxi- 



24 WATER EESOUECES OF EIO GKANDE BASIN, 1888-1913. 

mate position of these lines. In the eastern part of New Mexico 
the relation between the two is fairly well defined and is shown on 
the map. No attempt was made to show local areas of high pre- 
cipitation due to detached mountain ranges as the data were too 
meager. For the higher altitude in the mountains northeast of 
Santa Fe, use was made of records as short as five and six years. 

The lines show the mean distribution of rainfall in New Mexico 
for the 10-year period 1903-1912, which, as explained on page 22, will 
probably not differ more than 2 inches for the mean variation for a 
much longer period. The chief characteristics of the distribution 
are the narrow belts of low precipitation following the Rio Grande 
and Pecos Valleys and the two areas of high precipitation, one in the 
mountainous region just north of Las Vegas, where means of 24 
inches were obtained, and the other in the area of high altitude on 
the western edge of the Pecos basin in Otero, Chaves, and Lincoln 
Counties, where a mean of 23 inches was recorded. For the remain- 
der of the State the precipitation (with the exception of the isolated 
mountain ranges) ranges from 11 to 17 inches. 

In Texas the lines of precipitation are not so well defined as in New 
Mexico and are probably several inches lower than the mean for a 
long-time period. It is seen that the precipitation increases fairly 
uniformly from 9 inches near El Paso to 19 inches at the mouth of 
the Pecos. From that point to the eastern edge of Starr County it 
rapidly increases to 25 inches at the mouth. 

E,ELATTON BETWEEN PRECIPITATION AND RUN-OFF: 

Comparison between precipitation and run-off for the various parts 
of the United States has been made by Henry Gannett, of the United 
States Geological Survey, who found that where the annual precipi- 
tation is less than 20 inches no definite relation exists, as apparently 
the needs of vegetation require that much. With less than this 
amount of precipitation the run-off will depend almost entirely on 
the intensity of the rainfall rather than upon its total annual amount. 
Short violent storms will cause a comparatively large percentage of 
the precipitation to run off as surface water, whereas the same or 
even a larger total precipitation occurring as gentle showers may 
have practically no run-off, the water finding its way into under- 
ground channels, evaporating, or being absorbed by vegetation. As 
there are only a few points in the Rio Grande basin where the annual 
rainfall exceeds 20 inches, it is seen that no definite relation exists 
between precipitation and run-off. Any possible relation is still fur- 
ther complicated by diversion of the waters for irrigation and by the 
large nonproducing areas in the upper parts of the drainage area. 



GENERAL FEATURES OF RIO GRANDE BASIN. 25 

FORE STATION.' 

By far the greater part of the forested areas in the Rio Grande 
basin in Colorado, and to a somewhat less extent in New Mexico, are 
included in the national forests. Data concerning forested areas in 
Texas and Mexico are lacking, but in Texas, at least, these areas are 
relatively unimportant. 

The headwater area in Colorado contains three national forests. 
Of these the Cochetopa lies in the basins of the Saguache and other 
tributaries of the San Luis, whose waters do not reach the Rio Grande 
at least as surface run-off, so that this forest may be disregarded in 
considering the effective area with respect to the Rio Grande. The 
San Isabel Forest may be disregarded for the same reason, as it 
embraces the northern part of the Sangre de Cristo range, from which 
no surface run-off reaches the Rio Grande. The Rio Grande Forest 
includes practically all the mountainous area in Colorado which con- 
tributes surface run-off to the Rio Grande, except a relatively 
small section in the southern part of the Sangre de Cristo range, from 
which the surface run-off per square mile is considerably less than 
from the other mountainous areas. The area of the Rio Grande 
Forest is 1,858 square miles. 

Owing to a number of causes, such as areas above timber line, open 
parks and grassy plains within the timber, and areas burned over by 
forest fires not more than 59 per cent, or 1,100 square miles, of the 
area within the forest can be considered timbered. The various types 
of timber with the relative area of each are given in the following 
table :

The diversity of the forest cover varies with species and types. 
Tolerant species — those which endure much shade — will, of course, 
cause much more shade and permit a more dense growth than an 
intolerant species. The Ehgelmann spruce is very tolerant of shade,

26 WATER EESOUECES OF RIO GRANDE BASIN, 1888-1913. 



and yellow pine is most intolerant. In a scale of 10 the following 
table will probably illustrate very closely the density of the different 
types of forest cover: 

Density of forest cover in Rio Grande Forest. 

Density (in a scale of 10). 

Engelmann spruce 7 

Douglas fir 5 

Western yellow pine 3 

Pinon 3 

Willows and aspen 8 

The foregoing tables indicate that the species having the greatest 
density of growth — namely, Engelmann spruce, willows, and aspens — 
cover nearly 1,000 square miles, and the species having a very much 
lighter growth cover 110 square miles. About 758 square miles within 
the forest lack forest cover. 

In New Mexico the forested areas are found only in the mountain- 
ous sections, as on the plains the rainfall is too small to permit timber 
growth. In the area drained by the Rio Grande above El Paso the 
forested area amounts to approximately 10,000 square miles, of which 
7,000 square miles are included in the national forests. It is impos- 
sible to give a close estimate of the amount of open land in the for- 
ests, but it is probably between 25 and 35 per cent. Assuming 30 
per cent as land not timbered, the effective area within the 10,000 
square miles would be reduced to 7,000 square miles. In these forests 
the denser species, such as spruce, willows, and aspens found in Col- 
orado, comprise a very much smaller area of forest, and therefore 
the forests in New Mexico are much more open than those in Col- 
orado. The many streams which sink into the ground before reach- 
ing the Rio Grande make it almost irdpossible to state with any 
degree of accuracy the effective forest area covering drainage basins 
whose waters actually reach the Rio Grande. 

POPULATION. 

The Rio Grande drains a section of the United States that is very 
sparsely settled. The following table, compiled from the reports of 
the Bureau of the Census, shows a population of the drainage by 
counties for 1910, 1900, and 1890, and the population per square mile:

a Not wholly within Rio Grande drainage basin. 

In the headwater region, where mining is the chief industry, the 
population is about 1 per square mile and shows a decrease with the 
decline of tliat industry. The agricultural region, comprising 
Saguache, Rio Grande, Costilla, and Conejos counties, Colo., chiefly 
in the San Luis Valley, showed a substantial increase from 1900 to 
1910 and, as might be expected, has a considerable denser population. 
The New Mexico part has shown a slow increase in population except 
in the southeastern quarter of the State, where the increase has been 
rapid, largely owing to the extension of irrigation, especially in 
Chaves and Eddy counties. The most thickly settled section is the 
north-central part of the State where irrigation has been carried on 
extensively for many years. Here the density is 5.3 per square mile 
for Taos, 7.5 for Santa Fe, 4.8 for San Mguel, and 19.4 for Bernalillo. 
The other sections where the density is from 1 to 3 per square mile are 
chiefly given over to stock raising, although in the valleys along the 
Rio Grande itself there are many thousand acres of irrigated land. 

The most sparsely settled section of the entire drainage area is the 
trans-Pecos region of Texas and the counties bordering it on the east. 
Here the average density of population is less than 1 .0 per square mile. 
Leaving the high plateau region and coming to the coastal plain the 
density increases from 2.6 per square mile in Kinney County to 4.1 in

Maverick, 7.0 in Webb — falls off to 3.0 in Zapata, increases to 4.9 
in Starr and 6.0 in Hidalgo Bounties. In general, the rate of increase 
has been greater in Texas than in either New Mexico or Colorado. 

THE RIVER.^ 

GENERAL FEATURES. 

The Rio Grande rises near the crest of the Continental Divide on the 
eastern slope of the San Juan Mountains in Colorado, at an elevation 
of approximately 12,500 feet above sea level, takes a general south- 
easterly course, and discharges into the Gulf of Mexico, a few miles 
east of Brownsville, Tex, From its source the river foUows an 
easterly course through a narrow canyon-like valley nearly to Del 
Norte, where the steep sides of the valley recede to inclose the large, 
level park-like region known as the San Luis Valley, which extends 
for a distance of 150 miles north to south with maximum width of 50 
miles, and through which the river flows for the most part between 
low banks. From Del* Norte the general course of tlie Rio Grande 
is southeastward to Garland Junction, where it becomes southward. 

Four miles above the Colorado-New Mexico hne, at the lower end 
of San Luis Valley, the river enters a canyon locally known as the 
Rio Grande Canyon, which continues to the head of Espanola Valley 
near Embudo. This canyon increases in depth from 100 feet at the 
State Hne to 700 feet near the mouth of Rio Hondo and appears from 
above as a gash in an otherwise level mesa. The fall of the river 
through the canyon is about 30 feet per mile. For a large part of its 
remaining course the stream passes through a succession of valleys 
or erosion basins which are separated by rock canyons and are limited 
in form and size by the character of the material in which they were 
excavated. 

From the lower end of the Rio Grande Canyon the river flows 
through Espanola Valley (which is 3 to 4 miles wide and extends to 
a point near San Ildefonso) and enters White Rock Canyon, a narrow 
gorge, about 20 miles long and in places 500 feet deep, which owes 
its existence to sheets of hard igneous rock that protect the under- 
lying sands and gravels. The fall in this canyon is about 10 feet per 
mile. 

At a point almost directly west of Santa Fe, the river enters Santo 
Domingo Valley, through which it flows to the upper end of San 
FeUpe Canyon, 7 miles south of the Indian pueblo of Santo Domingo. 
This vaUey is 1 to 3 miles wi.de and contains about 13,000 acres of 
bottom land that has been irrigated for many years. The greater 
part of this land Ues only a few feet above the bed of the river and is 
subject to frequent overflow. 

1 The description of the part of the drainage basin in New Mexico is taken largely from Lee, W. T., Water 
resources of the Rio Grande Valley in New Mexico: U.S. Geological Survey Water-Supply Paper 188, 1907. 



THE EIVER. 29 

Passing: throii2:h San Felipe Canyon, which is a short gor^e, the 
river entei-s Albuquerque Valley, through which it flows for a distance 
of about 35 miles until it reaches Isleta Narrows. Albuquerque 
Valley ranges in width from 1 to 5 miles and comprises approxi- 
mately 70,000 acres of bottom land. It is bounded on both sides by 
steep bluffs of sand and gravel. 

The narrowing at Isleta Narrows is caused by the presence of the 
hard igneous rock of an extinct volcanic cone west of Isleta. Below 
the narrows the river flows for 45 miles through Belen Valley, which 
extends to San Acacia and contains approximately 65,000 acres of 
bottom land. 

From Belen Valley the river passes through San Acacia Gorge — a 
short, narrow gorge, 250 feet deep, cut through an arm of the lava 
sheet which crosses the river course — and entei-s Socorro Valley, 
which extends southward to San Marcial, a distance of 40 miles and 
comprises about 60,000 acres of bottom land. 

Beginning a short distance below San Marcial is a narrow vaUey, 
about 40 miles long, which is cut in detritus and which differs from 
the othei-s in being very narrow and having no bottom lands. This 
valley is the site of the Engle reservoir under construction by the 
United States Reclamation Service. A few miles north of Elephant 
Butte the river enters a narrow rock canyon which extends to the 
end of the Caballos Mountains and in which, opposite Elephant Butte, 
is the Engle dam site. 

Below Elephant Butte Canyon the Rio Grande flows through Las 
Palomas Valley to Rincon, a distance of 50 miles. The bottom lands 
in this vaUey include approximately 26,000 acres. From Las Palomas 
Valley the river enters Selden Canyon, which is 18 miles long but is 
not so uniformly narrow as the previous canyons, containing about 
8,000 acres of bottom land. 

Emerging from Selden Canyon at old Fort Selden, the river enters 
Mesilla Valley, the largest of the erosion basins of the Rio Grande, 
extending southward 50 miles to The Pass. The valley has a maxi- 
mum width of 8 miles and contains approximately 150,000 acres of 
bottom land. It is cut in unconsoUdated sand and gravel, its floor 
being 300 feet lower than the mesa level. 

Below Mesilla Valley, just above El Paso, the river flows through 
a narrow gorge about 90 feet deep, cut in a low ledge of hard rock. 

From El Paso to its mouth the river forms the boundary between 
the United States and Mexico. For a distance of 100 miles below El 
Paso it flows in a broad lowland known as El Paso Valley, 250 feet 
below the general upland level. This plain becomes gradually nar- 
rower, until it terminates at a point 100 miles southeast of El Paso 
and the river cuts through a narrow gorge, 5 miles long, formed by 
the southeastern extension of the Quitman Mountains. 



30 WATER EESOURCES OF EIO GEANDE BASIN, 1888-1913. 

Below the canyon is another broad valley, 16 miles long, which 
terminates a few miles above the mouth of Glenn Creek. For the 
next 60 miles the river flows through a mountainous region where the 
valley is narrow and in many places gorgelike. Near Ruidoso the 
mountains recede, leaving a broad valley with comparatively gentle 
side slopes. This characteristic of the topography continues for the 
next 60 miles (measured in a straight hne) until at a point about 20 
miles below Presidio the river again enters a canyon. Thence to the 
fall line, near Del Rio, the river flows through a succession of canyons 
and narrow valleys, with an occasional area in which the mountains 
are sufficiently far apart to include valleys of considerable area. 

From Del Rio to the mouth the river flows through the coastal 
plain region, which is characterized by comparatively low topographic 
reUef, and a few miles east of Brownsville, Tex., it discharges into the 
Gulf of Mexico. 

TRIBUTARIES. 

Above San Luis Valley the tributaries of the Rio Grande are 
perennial mountain streams, the most important (named in descend- 
ing order) being Pole, Lost Trail, Glear, Crooked, Calma, Willow, and 
Hot Spring creeks and the South Fork. Little water is diverted from 
the Rio Grande and its tributaries before it enters the valley, so the 
flow at that point represents the natural run-off from approximately 
1,200 square miles of mountain area ranging from 8,000 to 14,000 feet 
in altitude. 

Through San Luis Valley the Rio Grande received no perennial 
tributaries from the north and east as the run-off from the Saguache 
and tributaries which drain the northern part of the valley is lost by 
seepage and evaporation before reaching the river. The Trinchera 
and the Culebra, which enter from the east, together with the Costilla, 
which enters from the west just south of the Colorado-New Mexico 
line, are important tributaries during the spring run-off and after 
heavy rains but are dry during portions of the year. From the west 
are received the waters of Wolf, Los Pinos, and San Francisco creeks 
in the vicinity of Del Norte, and Rio Alamosa, La Jara Creek and 
Conejos River, none of which, although perennial streams, represents 
the natural run-off from its drainage area on account of the many 
irrigation diversions and the possible seepage losses in crossing the 
valley. 

Between the State line and the mouth of Chama River the only 
perennial tributaries of importance are Rio Colorado, Rio Hondo, 
Embudo Creek, and Rio Taos. Chama River, which enters the Rio 
Grande at Chamita, is one of the most important tributaries of the 
upper river. From Chamita to Albuquerque the only noteworthy 
tributaries are Santa Cruz, Santa Clara, San Ildefonso, and Jemez 



RIO GRANDE, 31 

rivers. As the Santa Cruz and San Iklefonso have their source in the 
Sangre de Cristo Mountains they are probably perennial streams, 
although confirmatory records are lacldng. The Jemez, which enters 
a short distance above Bernalillo, carries but little water to the 
Rio Grande except during the spring floods. 

The eft'ect that underground sources have upon the flow of the 
river is shown by the various seepage measurements made. 
(See p. 679.) 

From Albuquerque to El Paso the Rio Grande has no important 
perennial tributaries. The largest flood stream is Rio Puerco, which 
drains a large area but is dry at its mouth the greater part of the year. 
There are many smaller flood-water tributaries, such as the Alamosa, 
CuchiUo, Negra, Palomaso, Seco, Las Animas, and Percha, all entering 
from the west. The drainage from the east with the exception of a 
very small part, is cut off by the interior basin known as the Jornada 
del Muerto (see p. 20). Thi-oughout New Mexico, and, to a less 
extent, the trans-Pecos region of Texas, the tributary run- off comes 
chiefly in the form of flood flow following torrential rains. Note- 
worthy perennial tributaries are also lacldng in the Texas part of the 
drainage basin between El Paso and the Pecos, which enters the Rio 
Grande about 40 miles northwest of Del Rio. Devils River, which is 
also a perennial stream enters a short distance above Del Rio. Below 
Devils River the basin is so narrow that tributaries are unimportant. 

Little information is available regarding the Mexican part of the 
drainage area beyond the fact that the only noteworthy tributaries 
are Rio Conchos, which enters nearly opposite Presidio, and Rio Salado 
and Rio San Juan, which enter below Laredo.

Location. — In sec. 13, T. 40 N., R. 4 W., in the Rio. Grande National Forest, about 
30 miles southwest of Creede, a short distance above mouth of Squaw Creek. 

Records available.— June 18, 1909, to September 30, 1913. 

Drainage area. — 163 square miles (measured from topographic sheets). 

Gage. — Chain gage, 200 feet upstream from Thirtymile Bridge, washed out October 5, 
1911. The flood of this date changed the mouth of Squaw Creek, making it enter 
above the gaging station. For that reason when the records were resumed April 
8, 1912, a vertical staff gage was established a quarter of a mile above the old site 
and above the new mouth of Squaw Creek. The relation between the gages was 
not determined. 

Channel. — Apparently permanent at new site. 

Discharge measurements. — Made from car and cable, except during low stages, 
when they are made by wading. 

Winter flow. — Ice causes backwater during the winter months and records are 
discontinued. 

Diversions. — So far as known no water is diverted above the station, and therefore 
the records represent the natural run-off.

WATER RESOURCES OF RIO GRANDE BASUsT, 1888-1913. 



Storage. — A short distance above the station the San Luis Valley irrigation district 
is constructing a reservoir of 43,000 acre-feet capacity which, when completed, 
will materially modify the flow of the river. During the low water of 1912 the 
operation of the reservoir gates controlled the flow somewhat, and during 1913 the 
flow was almost wholly controlled. 

Accuracy. — Owing to the high altitude at this point it is possible that at certain 
seasons of the year the alternate melting and freezing may cause considerable 
diurnal fluctuation. For this reason the mean daily gage height taken from 
morning and evening readings may not represent accurately the true mean for 
the day. With this exception, conditions are favorable for accurate results and 
the records as a whole are considered good.^ 

Cooperation. — Station maintained in cooperation with Mr. J. C. Ulrich, of the San 
Luis Valley irrigation district, by whom the field data were furnished.

RIO GRANDE NEAR CREEDE, COLO. 

Location. — In the Rio Grande National Forest, at highway bridge about sec. 8, T. 

41 N., R. 1 E., one-quarter mile from Wason siding, and 3 miles east of Creede. 

Nearest tributary, Willow or Goblin Creek, enters a short distance upstream. 
Records available.— April 24, 1907, to September 30, 1913. 
Drainage area. — 705 square miles. 
Gage. — An automatic recording gage, referred to the same datum as the chain gage 

used previously. 
Channel. — Practically permanent. 
Discharge measurements. — Made from bridge. 
Winter flow. — River frozen over during winter months; ice causes backwater at 

gage and discharge measurements are made to determine the winter flow. 
Diversions. — There are no court decrees for diversions from the Rio Grande above 

this station, but for diversions of 39 second-feet from tributaries. There are no 

reservoirs on the river between this station and the one at Thirtymile Bridge, but 

a large one is being built on Clear Creek, which enters between. 
Accuracy. — Records good.

RIO GRANDE NEAR DEL NORTE, COLO. 



Location. — At highway bridge, about sec. 29, T. 40 N., R. 5 E., 6 miles west of Del 
Norte, a short distance below the mouth of Wolf Creek. 

Records available.— April 16, 1908, to September 30, 1913. From July 1, 1889, 
to November 30, 1906, a station was maintained about 4 miles below the present 
station and just above Los Pinos Creek. The flow at the two points is not directly 
comparable, as a number of small streams contribute water during certain seasons, 
and a small amount of water is diverted for irrigation. 

Drainage area. — Approximately 1,400 square miles. 

Gage. — Automatic recording gage, the property of the State engineer, installed 
November 8, 1910. This gage is referred to the same datum as was the chain gage 
installed May 16, 1908. The gage datum used at the original station remained 
unchanged. 

Channel. — Shifting from year to year. 

Discharge measurements. — Made from bridge at present station and from car and 
cable at original site. 



EIO GRANDE. 



47 



Winter flow. — River is frozen over during the winter monttie, and measurements are 
made to determine the approximate discharge. 

Diversions. — There are court decrees for diversions of 101 second-feet from the Rio 
Grande between the Creedeand Del Norte stations, and for diversions of 162 second- 
feet from intervening tributaries. 

Cooperation. — Station maintained since 1910 in cooperation with the State engineei, 
who furnished complete the records for 1912 and 1913. 

Discharge measurements of Rio Grande near Del Norte,- Colo., in 1889-1913.

Note.— Prior to 1899 there were no ice note.s in the original records, and it is probable that the gage read- 
Inijs were taken to the top of the ice. The ice period for each winter is somewhat uncertain, but its begin- 
ning has been determined from the rise due apparently to backwater from ice which occurred either in 
November or December. Its ending hns been deterrnined from the drop in gago heights usually in 
March, which denote open-channel conditions, as the spring break-up is not attended by any considerable 
rise.

Note. — A study of the winter discharge measurements and gage heights during the winter period from 
1910 to 1913 shows that the fiow decreases slowly to Feljruary when it reaches a minimum, and remains 
low until the ice breaks up. This is due to the high altitude of the drainage area above the stations, which 
prevent practically any precipitation from entering the streams during that period — the groimd water 
being the chief source of supply. With this as a basis and as comparison with the records at Embudo which 
are practically free from ice, winter estimates for the earlier years have been made lny gradually reducing 
the dischargefrom that at which the ri\er froze over in the fall. It is not intended that these earlier winter 
estimates should l)e considered as reliable in determining the minimum flow in the Rio Grande, but rather 
that they should be used in coimection with the total yearly flow. 

Discharge records for 1912 and 1913 furnished by the State engineer. 

RIO GRANDE AT ALAMOSA, COLO. 



Location. — At the railroad bridg? half a mile east of Alamosa. The nearest tributary 

is Rio Alamosa, which enters about 6 miles below. 
Records available. — Discharge measurements and gage heights September 28, 1894, 

to December 31, 1895. Miscellaneous measurements, 1903 and 1910. Complete 

records, May 15 to December G, 1912, April 29 to September 30, 1913. 
Drainage area. — Not measured. 
Gage. — Vertical staff. 
Channel. — Data too meager to determine. 
Discharge measurements. — Made from highway bridge a quarter of a mile above 

the railroad bridge. 
Diversions. — Below most of the large diversions from the Rio Grande in Colorado. 
Accuracy. — Data insufficient for estimates of discharge except for 1912. 
Cooperation. — During 1912 and 1913 the station was maintained by the United 

States Reclamation Service, by which the complete records were furnished.

Note. — The earlier records contained no notes in regard to ice, and the gage heights taken when the 
river was frozen over were probably read to tlie surface of the ice. From the best available evidence it 
is probable that backwater from ice occurred as follows: Nov. 22, 1899, to Mar. 4, 1900; Nov. 18, 1900, to 
Mar. 8, 1901; Nov. 18, 1901, to Mar. 9, 1902; Dec. 10-27, 1902; Nov.. 11, 1903, to Mar. 6, 1904; Nov. 13, 1904, 
to Mar. 6, 1905; Nov. 8, 1905, to Mar. 7, 1906; Nov. 25, 1906, to Mar. 4, 1907; Dec. 14, 1907, to Feb. 29, 1908; 
Nov. 18, 1908, to Mar. 1, 1909; Dec. 5, 1909, to Mar. 2, 1910; Dec. 7, 1910, to Feb. 28, 1911; Nov. 7, 1911, to 
Mar. 2, 1912. Station discontinued during winter of 1912-13.

Note. — The discharge for 1899 are based on a rating curve not well defined. Tlie estimates for 1900 to 
1902, inclusive, liave been revised since being published originally and are based on a fairly well defined 
rating curve. The 1903 discharges are based on a rating curve that is not well defined, and they are prob- 
ably too large between 200 and 3,000 second-feet. The 1904 discharges are based on a rating curve that is 
well defined below 600 second-feet but somewhat uncertain above. The discharges from March, 1905, to 
Apr. 16, 1907, are based on a well-defined curve. The discharge from Apr. 17, 1907, to November, 1908, are 
based on a curve that is well defined above 200 second-feet. The 1909 and 1910 discharges are based on a 
well-defined rating curve. The 1911 discharges are based on a well-defined rating curve. Discharges of 
1912 and 1913 were furnished by the State engineer.

Note.— A study of the winter discharge measurements and .gage heights from 1908 to 1912 shows that 
the winter estimates for the earlier years were too large. The evidence regarding the winter flow at the 
Lol>atos station now shows that the flow increases gradually from the time the river freezes over until 
January, and from that time gradually decreases until the winter brealaip. This evidence is corroborated 
by the measurements made during the winters of 190S-1909, 1909-1910, 1910-1911, 1911-1912. Measurements 
made in 1913 apparently contradict the above evidence, probably because both ice measurements in 1913 
were made after periods of severe cold weather, when the flow was temporarily reduced below the average 
amount. 

Subsequent to 1910 the winter estimates have been based almost directly on the discharge measure- 
ments. From 1899 to 1903 the estimates were based chiefly on the flow at Eihbudo which was practically 
unaffected by ice, an allowance ranging from 150 to 250 second-feet being made for the increased flow be- 
tween the two points. From 1904 to 1909 the winter estimates were based chiefly on the low-water flow 
in the fall before the river froze over. Comparison being made with the same conditions at the Del Norte 
station. 

Prior to 1910 the winter estimates are uncertain owing to insufficient data, and can only be considered 
approximate. Those for 1904 to 1909 are only roughly approximate and have been given merely to complete 
the yearly record. 

Records for 1911-13 furnished by the State engineer.

WATER EESOUECES OP EIO GKAiSTDE BASIN, 1888-1913. 



RIO GRANDE AT EMBUDO, N. MEX. 

Location. — At Santa Barbara Tie & Pole Co.'s bridge, a few hundred feet below the 
Denver & Rio Grande Railroad eating house at Embudo, at the mouth of the box 
canyon at the entrance to Espanola Valley, near sec. 27, T. 23 N., R. 9 E. The 
nearest tributary, Santa Barbara Creek, joins the Rio Grande about 3 miles above 
the station. 

Records available.— December 21, 1888, to December 31, 1903; September 8, 1912, 
to September 30, 1913. 

Drainage area. — Approximately 10,100 square miles. 

Gage. — Automatic recording. From January 1 to February 28, 1889, a gage was 
maintained 1 mile above Embudo, but moved to a point 1,500 feet above the site 
of the present gage March 1, 1889, and used until December 3,1903. The datum 
of this gage remained unchanged from March 1, 1889, to December 31, 1903. On 
September 8, 1912, an automatic gage was installed which was referred to a new 
datum. 

Channel. — Subject to a change during flood stages, but fairly permanent at low stages. 

Discharge measurements. — By wading at low stages and from a cable during flood 
and medium stages. 

Winter flow. — Relation between gage height and discharge during the winter months 
little, if any, affected by ice. 

Diversions. — Between Lobatos station and Embudo the Rio Grande flows through a 
canyon, so that there is practically no diversions from the river. 

Accuracy. — Estimates of daily discharge for 1912 can be considered only fair; those 
for 1913 are good. 

Cooperation. — During 1912 and 1913 station maintained in cooperation with the 
State engineer; prior to that date by the United States Geological Survey alone. 

Discharge measurements of Rio Grande at Embudo, N. Mex., in 1889-1903, 1912-13.

Note. — The old records contain no notes concerning ice. The flow for the winter months, computed as 
for open-channel conditions, compared with the winter flow at the Lobatos station and the intervening 
tributaries shows substantial agreement, indicating that if ice is present the effects are slight. 

Gage height slightly affected by ice Dec. 21, 1912, to Jan. 17, 1913. 

Daily discharge,in second-feet, of Rio Grande at Emhudo, N. Mex.,for 1889-1903, 1912-13.

Note. — Daily discharge determined as follows: 1889 to 1894, from a rating curve that is not well defined 
on account of shifting channel and any single estimate may be 10 per cent or more in eiTor, but these errors 
are compensating; 1895 and 1896, from a rating curve somewhat better defined than that for 1889 to 1894; 
1897, from three fairly well-defined rating curves, the first used from Jan. 1 to Apr. 18, the second from 
Apr. 19 to Aug. 21, and the third from Aug. 22 toDec. 31; 1898, from a rating curve not well defined above 
1,000 second-feet; 1889, from a well-defined curve. Estimates for 1900 and 1901 have been revised. Those for 
1900 are based on a rating curve well defined below 3,500 second-feet; those for 1901 are based on two well- 
defined rating curves, one used from Jan. 1 to July 27, and the other used for the remainder of the year. 
Daily discharges for 1902 and 1903 were ftirnished by the International Water Commission and are based 
almost directly on the discharge measurements. Daily discharge for 1912 determined from two fairly well- 
defined rating curves, and that for 1913 from a curve well defined except for the period Mar. 17 to Apr. 1, 
when the indirect method for shifting channels was used. The daily values for 1913 represent the mean 
of 24 hourly discharges and not the discharge obtained from the daily mean gage height. Dec. 21, 1912, to 
Jan. 17, 1913, estimated on account of ice.

WATER EESOURCES OF EIO GEANDE BASIN, 1888-1913. 



RIO GRANDE NEAR BUOKMAN/ N. MEX. 

Location. — At the Denver & Rio Grande Railroad bridge, at the head of White Rock 
Canyon, 4 miles above Buckman, 2 miles below the Indian village of San Ilde- 
fonso, about sec. 18, T. 19 N., R. 8 E. The nearest stream is Tesuque Creek, 
which enters near San Ildefonso. There is an arroyo just above the station. 

Records available.— February 1, 1895, to December 31, 1905; June 23, 1909, to 
September 30, 1913. 

Drainage area. — Not measured. 

Gage. — Automatic recording gage installed in June, 1910. The original gage was 
located on the left bank, 180 feet above the bridge. On March 30, 1904, avertical 
staff gage was established at the bridge at a datum 2.02 feet higher than the original 
datum. The datum of the present gage is the same as that of the gage established 
in 1904. 

Channel. — Shifting, as a result of scour and fill of sand on lava bowlders. 

Discharge measurements. — Made from car and cable originally located near the 
gage, but moved 3 miles below the gage in 1910. No diversions or important 
tributaries between the two points. 

Winter flow. — Only slightly affected by ice. 

Diversions. — Between Embudo and Buckman the bottom lands in Espanola Valley 
are u'rigated extensively. In 1896 W. W. Follett, of the International Water 
Boundary Commission, reported that ditches having a capacity of 406 second-feet 
diverted water from the Rio Grande between the two points. 

Accuracy. — Prior to the flood in October, 1911, conditions were favorable for accurate 
results, but the flood caused considerable change which was not fully covered by 
field work. Thus the estimates from October, 1911, to May 1, 1912, can not be 
considered better than fair. The records thereafter can be considered good. 

Cooperation. — Station maintained in cooperation with the State engineer during 
1912 and 1913.

Note.— Daily discharge determined from rating curves which cover short periods and are for the most 
part not very well defined, and by the indirect method for shifting channels. During 1895 the discharge 
for days for which gage heights are missing was obtained by interpolation. Discharge estimated Dec. 11, 
1912, to Jan. 6, 1913, on account of ioe.

RIO GRANDE NEAR SAN MARCIAL, N. MEX. 

Location. — At the Atchison, Topeka & Santa Fe Railway bridge, 1 mile south of San 
Marcial, in sec. 19, T. 7 S., R. 1 W. No important tributaries enter in the imme- 
diate vicinity of the station. 

Records available. — January 29, 1895, to September 30, 1913. 

Gage. — Inclined staff gage established January 29, 1895, and carried away by flood 
in 1896. A wire gage was established in its place at the same datum. This was 
soon abandoned and the gage heights have since been measured with a graduated 
rod from the bridge deck to the water surface. The gage datum of the inclined 
staff and wire gages is still used . 

Channel. — Sandy and very shifting; current broken by a number of bridge piers. 

Discharge measurements. — Made from the downstream side of the bridge. 

Diversions. — Between Buckman and San Marcial the bottom lands along the river 
are extensively irrigated. In 1896 W. W. Follett, of the International Boundary 
Commission, estimated that ditches having a capacity of 1,779 second-feet diverted 
water from the Rio Grande between these points. 

Cooperation. — Station maintained since 1901 by the American section of the Inter- 
national Water Commission, by whom the records are furnished.

RIO GRANDE NEAR EL PASO, TEX. 

Location. — Original station located at Old Fort Bliss, about 1,500 feet above the 
Mexican dam. Observations made from May 10, 1889, until end of June, 1893. 
January 25, 1895, the station was reestablished at the pumping house of the 
Smelter Co., 3 miles north of El Paso. On May 1, 1897, it was moved 1 mile 
upstream to Courchesne's limekiln, its present location. 

Records available.— May 10, 1889, to June 30, 1893; January 25, 1895, to September 
30, 1913. 

Drainage area. — Not measured. 

Gage. — A vertical staff was used originally, but at the present location a number of 
inclined gages located at slightly different points but referred to the same datum 
have been used. 

Channel. — Extremely shifting and subject to overflow. 

Discharge measurements. — Made from car and cable. 

Winter flow. — Relation between gage height and discharge not affected by ice. 

Diversions. — Between San Marcial and El Paso the bottom lands along the river, 
chiefly in La Palomas and Mesilla valleys, are irrigated extensively. In 1896 
W. W. Follett, of the International Water Commission, estimated that ditches 
having a capacity of 97.4 second-feet diverted water from Rio Grande between 
those points. The United States Reclamation Service is constructing a reservoir 
at Elephant Butte, which will have a capacity of 2,627,000 acre-feet, to be used 
in irrigating land in the Rio Grande valley. 



mo GRANDE. 



I6ii 



Accuracy. — Owing to the shifting channel, discharge measurements are made very 
frequently, and the estimates of daily discharge based almost entirely on these. 

Cooperation. — Since May 1, 1897, the station has been maintained by the United 
States section of the International Water Commission, by whom the records are 
furnished .

RIO GRANDE ABOVE PRESIDIO, TEX. 

Location. — At the Haciendita, 9 miles above Presidio, and 8 miles above the mouth 
of Rio Conchos, one of the principal tributaries of the Rio Grande. On September 
26, 1905, the station was moved 8 miles farther upstream and maintained at that 
point until July 6, 1909, when it was removed to the original site. As no tribu- 
taries enter between the two points the flow is the same at both sites. 

Records available.— May 22, 1900, to September 30, 1913. 

Drainage area. — Not measured. 



204 



WATER RESOURCES OF RIO GRANDE BASIK, 1888-1913. 



Gage. — Inclined staff. Relation between the gage readings at the two sites or 
between the two gages used at the present site not determined. 

Channel. — Shifting greatly.. 

Discharge measurements. — Made from car and cable. 

Diversions. — No data. 

Accuracy. — Owing to the shifting channel, discharge measurements are made very 
frequently and the estimates of daily discharge based almost directly on these. 

Cooperation. — Station maintained by the United States section of the International 
Water Commission, by whom the records are furnished. 

Discharge measurements of Rio Grande above Presidio, Tex., in 1900-1913.

RIO GRANDE BELOW PRESIDIO, TEX. 

Location. — At the west end of the canyon section of the Rio Grande, 6 miles below 
Presidio, and 7 miles below the mouth of the Rio Conchos. The discharge at 
this station minus the discharge at the station above Presidio is the discharge of 
the Rio Conchos, except at rare intervals, when some rain water enters the Rio 
Grande from the north. 

Records available. — May 1, 1900, to September 30, 1913. 

Drainage area. — Not measured. 

Gage. — Inclined staff in main channel and vertical staff at the gravel hills to measure 
the overflow. 

Channel. — Shifting sand, and is affected by an intermittent stream called Alamos 
Creek, which reaches the river one-fourth mile below the station. This creek 
is subject to torrential floods which bring large quantities of bowlders and gravel 
into the Rio Grande, forming a temporary dam that remains, throwing backwater 
onto the gage, until a flood in the river scours it out. The channel overflows at 
gage height 13 feet to an extreme width of 750 feet, where gravel hills are found. 

Discharge measurements. — Made in main channel from car and cable and in over- 
flow section from boat. 

Floods. — Below the mouth of the Rio Conchos the Rio Grande is subject to severe 
floods from this tributary. Since the records have been maintained the highest 
flood occurred September 11, 1904, reaching a stage of 26.35 feet and a discharge 
of 149,200 second-feet. On the same day the discharge above the Rio Conchos was 
only 2,600 second -feet. 



224 



WATER EESOUROES OF RIO GRANDE BASIN^ 1888-1913. 



Diversions.— No data. 

Accuracy. — Owing to the sMfting channel, discharge measurements are made very 

frequently and the estimated daily discharge is based almost directly on these 

measurements. 
Cooperation. — Station maintained by the United States section of the International 

Water Commission, by whom the records are furnished.

RIO GRANDE NEAR LANGTRY, TEX. 

Location. — At the east end of the canyon section, half a mile south of Langtry, and 
a few miles above the mouth of the Pecos. 

Records available. — May 1, 1900, to September 30, 1913. 

Drainage area. — Not measured. 

Gage. — Vertical staff. 

Channel. — Very shifting and subject to overflow at stage of 29.5 feet. The overflow 
extends 110 feet back of the main bank. 

Discharge measurements. — Made from car and cable. 

Floods. — Below the Rio Conchos the Rio Grande is subject to severe floods from that 
source. Since the records have been maintained the highest flood occurred Sep- 
tember 13, 1904, reaching a stage of 34.25 feet and a discharge of 132,000 second - 
feet. This is somewhat less than the maximum stage of 149,200 at the station 
below Presido, showing the slight retarding effect of the channel upon flood flow. 

Diversions. — No data. 

Accuracy. — Owing to the shifting of the channel very frequent discharge measure- 
ments are made and the estimates of daily discharge based almost directly on 
these. 

Cooperation. — Station maintained by the United States section of the International 
Water Commission, by whom the records are furnished.

RIO GRANDE AT EAGLE PASS, TEX. 

Location. — Half a mile above the highway bridge between Eagle Pass, Tex., and 
Ciudad Porfirio Diaz, Mexico. 

Records available.^ — May 1, 1900, to September 30, 1913. 

Drainage area. — Not measured. 

Gage. — Vertical and inclined staff. 

Channel. — Very shifting and subject to overflow for a width of 1,500 feet, beginning 
at a stage of 22 feet. 

Discharge measureinents. — Made from car and cable. 

Floods. — ^The maximum recorded flood occurred at midnight June 29, 1905, and 
reached a stage of 34.6 feet. The flood of September, 1904, reached a maximum 
24-hour stage of 23.1 feet with a corresponding discharge of 172,300 second-feet. 

Diversions. — No data. 

Accuracy. — Owing to the shifting channel, discharge measurements are made very

WATEE RESOURCES OP RIO GRANDE BASIN, 1888-1913. 



RIO GRANDE NEAR BROWNSVILLE, TEX. 

Location. — One mile above Brownsville, opposite Matamoras, Mexico. 

Records available.— April 29, 1900, to September 30, 1913. 

Gage. — Vertical staff. 

Chaimel. — Shifting. 

Discharge measurements. — Made from car and cable. 

Natural storage. — Between Roma and Brownsville there are many lagoons (old 
river channels) which take river water during moderate floods, and a large area is 
overflowed deeply in large floods. Much of this water returns slowly to the river 
as the floods subside, thus making the flow more uniform at Brownsville than at 
Roma. Large quantities also leave the river entirely, reaching the Gulf of 
Mexico by other channels. 

Accuracy. — Although frequent discharge measurements have been obtained, no 
estimates of daily discharge have been made by the commission. 

Cooperation. — ^This station is maintained by the Mexican section of the International 
Water Commission, by whom the base data are furnished. 

Discharge measurements oj Rio Grande near Brownsville, Tex., in 1900-191S.

WATER RESOURCES OF RIO GRANDE BASIN, 1888-1913. 



341 



SOUTH FORK OF RIO GRANDE BASIN. 



SOUTH FORK OF RIO GRANDE AT SOUTH FORK, COLO. 

Location. — At highway bridge, half a mile west of the South Fork station of the 
Denver & Rio Grande Railroad, in sec. 34, T. 40 N., R. 3 E. No tributaries 
between the station and the mouth and none for several miles above. 

Records available. — August 9, 1910, to September 30, 1913. Also a number of 
discharge measurements made in 1909 by the United States Geological Survey. 

Drainage area. — 21G square miles (State engineer's report). 

Gage. — Inclined staff. The original gage was washed out by flood October 5, 1911, 
and was replaced by a new gage October 16, at a different datum. May 12, 1912, 
a chain gage was established at the original location, but referred to a different 
datum. 

Channel. — Apparently permanent at present location. 

Discharge measurements. — Made from bridge. 

Winter flow. — Ice causes backwater during the winter months. 

Diversions. — There are court decrees for diversions of 11 second-feet from South Fork 
above the station; none below. 

Cooperation. — Station is maintained and records are furnished by the State engineer. 

The South Fork of the Rio Grande, a stream about 15 miles long, rises near Summit- 
ville, in Rio Grande County, and flows northward to its junction with the main stream 
at South Fork.

346 WATER RESOURCES OF RIO GRANDE BASIN, 1888-1913. 

SAN LUIS CREEK BASIN. 
GENERAL FEATURES. 

San Luis Creek rises in Poncha Pass at an elevation of about 9,000 
feet and flows southward across the San Luis Valley to the San Luis 
lakes. Although the San Luis itself rises at a comparatively low 
altitude, its numerous tributaries take their rise in the high moun- 
tains of the Sangre de Cristo and Saguache ranges at altitudes of 
12,000 feet and over. From the Sangre de Cristo the lai^er tribu- 
taries are Cotton, Wild Cherry, Rito Alto, San Isabel, Crestone, 
WiUow, Spanish, Cottonwood, Deadman, and Arena creeks. Many 
of the tributaries from the eastern range reach the San Luis. Of 
those from the western ranges — Saguache and La Garita — only 
Kerber and Saguache creeks reach it, the other streams sinking into 
the porous soil of the vaUey soon after leaving the mountains. 

The San Luis drains the northern part of the San Luis Valley, 
which may be considered an interior basin as no surface water escapes 
from it. The drainage of the northern part of the valley is toward the 
San Luis lakes, where the water is lost by seepage and evaporation. 
The old overflow channel to the Rio Grande still exists, but it has 
been so blocked by incipient sand dunes as to be almost obliterated 
in many places. 

The rock formations of the western boundary of the drainage area 
dip toward and extend beneath the valley, as in the Conejos Range 
described in connection with the Alamosa and Conejos drainage basins. 
Little is known of the geology of the Sangre de Cristo Range, which 
forms the eastern boundary of the drainage area, but the axis of the 
range is in general made up of intrusive granite flanked on both sides 
by conglomerate. 

Between the eastern boundary and the western, where the higher 
peaks reach elevations of 14,000 feet above sea level, is the high-level 
plateau comprising the San Luis Valley. The slope of the eastern 
range of mountains is much more abrupt than that of the western, 
so that the alluvial fans formed where the streams debouch onto 
the valley floor are much steeper on that side. From the axis of 
the valley, which is occupied by the channel of San Luis Creek, the 
country rises to the foothills, steeply eastward, very gently westward, 
at first not more than 3 to 6 feet to the mile, but gradually increasing 
until near the foothills the rise is quite perceptible to the eye. The 
floor, of the valley, ranging in elevation from 7,500 to 8,000 feet 
above sea level, is covered with a series of blue clays and inter- 
stratified sands which yield artesian water. Flowing wells are most 
numerous in the area drained by Saguache Creek. 



SAN LUIS CREEK BASIN. 



347 



Precipitation in the vSaii Luis Valley probably ranges from 16 to 
20 inches or more in the mountains to 13 inches at the upper end 
and 8 or 9 inches at the lower, but, owing to the porous character 
of the soil and to the lack of drainage channels, only a small part 
of the rainfall reaches the San Luis, the remainder being lost by 
seepage, as shown by the fairly abundant supply of underground 
water, and by evaporation. A general description of precipitation 
in the valley is presented on page 23. 

Tlie watei-s of the San Luis and its feeders are used for irrigation 
and are greatly overappropriated, there being adjudicated decrees 
for diversions of 1,900 second-feet, of which approximately 750 
second-feet are for diversion from the Saguache and its tributaries. 

So far as known the only reservoir that has been built in the basin 
is the State reservoir near Saguache. It has a capacity of 954 acre- 
feet, but as it has no adjudicated rights, and as the flood flow of the 
Saguache is entirely appropriated, it has not been used to any extent. 

GAGING STATION RECORDS. 
SAN LUIS CREEK AT VILLA GROVE, COLO. 

Location. — In sec. 12, T. 46 N., R."9 E, opposite Villa Grove post office, a short 
distance below the mouth of Kerber Creek. 

Records available.— July 30, 1911, to September 30, 1912. 

Gage. — Vertical staff. 

Channel. — Apparently permanent. 

Discharge measurements. — Made from footbridge. 

Winter flow. — Ice causes backwater during the winter and the records are discon- 
tinued. 

Diversions. — There are court decrees for diversions from San Luis Creek of 34 second- 
feet above the station and 111 second-feet below. 

Cooperation. — Station is maintained and records are furnished by the State engineer.

RIO ALAMOSA BASIN. 



GENERAL FEATURES. 



Rio Alamosa, one of the important tributaries of the Rio Grande 
in its upper course, rises in the Conejos Mountains at the western 
edge of the San Luis Valley, near the crest of the Continental Divide. 
Its general course is eastward across San Luis Valley, and it joins 
the Rio Grande about 6 miles below Alamosa. It has a few short 
tributaries in the mountainous part of its course but none after 
reaching the valley. 

The upper fourth of the Alamosa basin lies in the Conejos Range, 
where the elevations reach 12,000 feet and more above sea level and 
the river and its tributaries flow through narrow valleys. The detri- 
tus brought down from this mountainous section has been deposited 



356 WATER RESOURCES OF RIO GRANDE BASIN, 1888-1913. 

at its entrance to the valley in the form of an alluvial fan of sand or 
gravel, similar to those built up by practically all of the mountain 
streams entering the valley. As the gradients of the streams issu- 
ing from the Conejos Kange are not so steep as those of streams 
flowing from the Sangre de Cristo Range, the resulting fans are not 
so prominent. Across the valley the river flows in a shallow channel 
only a few feet deep, and owing to the porous character of the allu- 
vial fan it probably loses water by seepage after it leaves the moun- 
tains. 

The following description of the geology of the Alamosa basin is 
taken from ' 'Geology and water resources of the San Luis Valley," 
by C. E. Siebenthal: ' 

The western moimtains, the Saguache and Conejos ranges are made up on their 
eastern flanks, adjacent to the San Luis Valley, of alternations of gi-avel beds, andesitic 
flows, and rhyolitic tuffs cut through in places by dikes and volcanic necks of centers 
of effusion. These flows incline toward the valley with dips varying from 6° to 15°, 
and extend under it, being penetrated in some of the wells at the south end of the 
valley. [In the valley proper these flows are covered with a series of blue clays, 
having interstratified sand beds.] 

Alamosa Creek leaves the foothills about d miles west of Capulin, through a defile 
in the lava rim. The south side of the defile rises into a bluff a hundred feet high 
which is capped with pyroxenite-andesite 40 feet in maximum thickness. * * * 
The lower part is massive and lies upon a water-sorted conglomerate, at the contact 
with which the lava is much broken. Bowlders from the conglomerate seem to be 
drawn up into the lava, and it is penetrated by crevices and "chimneys" of loose- 
textured rock, apparently the result of steam escaping when the flow covered the con- 
glomerate. The conglomerate has a burnt, reddish color, and the sandy matrix is 
more or less consolidated and indurated. These gravel beds rise upstream and 300 
yards west come to the top of the bluff where they are interbedded with and under- 
lain by brecciated pumice or rhyoUtic tuffs. * * * [It is believed that a period 
of local glaciation antedated the last lava flow in this vicinity.] The Alamosa glacier 
manifestly occupied the U-shaped valley down nearly to the "box-canyon," spread- 
ing across the flat west of Chiquita Peak into the valley of Cat Creek. Below the 
"box-canyon" there are two terraces both developed on the south side of the valley. 
The lower one, apparently alluvial, is 60 feet high and 100 to 150 yards wide. The 
upper one, 30 feet higher, is covered with bowlders, in part glacial, and has an irreg- 
ular surface. * * * A mile farther down the creek a third terrace sets in 35 feet 
high above the valley bottom. 

Precipitation on the Conejos Mountains, in which the Alamosa 
rises, is heavier than in any other part of the region drained by the 
Rio Grande. At Platoro (elevation 9,800) the mean precipitation is 
upward of 23 inches, and at Summit (elevation 10,800) the mean for 
2 years shows approximately 36 inches. On the mountain summits 
it is probable that the precipitation is even greater, as it increases

which is the source of the high-water in the streams in May and

RIO Al.AMOSA BASIN. 



'rW 



Juno. Tlie precipitation in the valley part of tlie drainafije basin is 
ap])roximately 8 inclies. 

The only artificial storage on the Alamosa is that afforded by the 
Terrace reservoir, near Terrace post office in T. 36 N., R. 6 E. Its 
capacity is approximately 17,000 acre-foot at the present time, and 
it is designed to store the flood waters for use in irrigating lands in 
the Terrace Irrigation District. The waters of the Alamosa are used 
extensively for irrigation in the San Luis A'alley, there being court 
decrees for appropriation of 1,700 second-feet by direct diversion 
from the Alamosa,

RIO ALAMOSA NEAR MONTE VISTA, COLO. 

Location. — In the Rio Grande National Forest, in eec. 2, T. 36 N., R. 5 E., 28 miles 

southwest of Monte Vista, a short distance below the mouth of French Creek, and 

about 6 miles above the Terrace reservoir dam. 
Records available. — September 29, 1911, to June 4, 1912. 
Drainage area. — 91 square miles ^ (measured from Forest Atlas). 
Gage. — Vertical staff. 
Channel. — Data too few to be conclusive. 
Discharge measurements. — Made from bridge 1 mile above gage during high 

w^ater and by wading at ordinary stages. 
Winter flow. — No information. 
Diversions. — The station is above all diversions except a ditch and flume used for 

hydraulic power at Terrace reservoir, which takes water half a mile above. There 

are court decrees for diversions of 1,700 second-feet from Alamosa River below the 

station. 
Accuracy. — ConditiouB are favorable for fairly accurate results and the estimates are 

considered fair. 
Cooperation. — Station maintained in cooperation with the United States Forest 

Service.

Note.— Monthly estimates for the winter period based on two discharge measurements. 



RIO ALAMOSA AT TERRACE RESERVOIR, NEAR LA JARA, COLO. 

Location. — About 1,000 feet below the Terrace reservoir dam, in sec. 14, T. 36 N., 
R. 6 E., about 24 miles northwest of La Jara. No important tributary within 
several miles. 

Records available.— April 18, 1909, to October 22, 1912. 

Drainage area. — 120 square miles (State engineer's report). 

Gage. — Vertical staff located at lower end of box canyon. 

Channel. — Fairly permanent. 

Artificial control. — The flow from the reservoir is controlled by two 4-foot circular 
valves, and therefore the records, though they show the entire amount of the 
natural flow (less seepage and evaporation losses), do not represent the natural 
fluctuations. The total capacity of the reservoir is 17,000 acre-feet, of which 
about 7,000 acre-feet was utilized during 1912. 

Cooperation. — The records have been taken from the report of the State engineer, 
and were furnished by Mr. John E. Field, engineer for the San Luis Land and Irri- 
gation Co. 

Daily discharge, in second-feet, of Alamosa River at Terrace reservoir, near La Jara, Colo., 

for 1909-1912.

362 WATER EESOURCES OF EIO GRANDE BASIN, 1888-1913. 

CONEJOS RIVER BASIN. 

GENERAL FEATURES. 

Conejos River rises on the eastern slope of the Conejos Mountains, 
on the southwestern boundary of San Luis region near, the head- 
waters of the Alamosa, nearly at the crest of the Continental Divide, 
flows northeastward as far as Platoro, then makes a sharp turn to 
the south following that direction for 10 miles, when it gradually 
bears to the eastward and then northward, entering the Kio Grande 
at Austin, about 6 miles below the mouth of the Alamosa. Just 
east of Conejos the river divides and flows to a point east of Manassa 
in two channels which there unite. Three miles above the mouth 
it again divides and enters the Rio Grande at two points a mile or 
more apart. Within the mountains the Conejos has many short 
tributaries, but after reaching the valley it receives only one tribu- 
tary of importance, the Rio San Antonio. 

The upper third of the Conejos basin lies in the mountains, with 
elevations reaching 12,000 feet. The detritus brought down in this 
portion of the basin has formed a long alluvial fan at the point of 
debouching into the valley. This fan is in part confined between 
the Mogotes Mountains and the San Luis Hills and in part extends 
south of the latter into New Mexico. Owing to the porous character 
of the material of the alluvial fan, it Is probable that there is some 
seepage loss in the flow of the Conejos after leaving the mountains. 
The river flows across the San Luis VaUey in a shallow channel, skirt- 
ing the western edge of the San Luis Hills. 

The mountains of the Conejos Range, which comprise the upper 
third of the area drained by the Conejos, are made up in their eastern 
slopes (adjacent to the valley) of alternations of gravel beds, ande- 
sitic flows, and rhyolitic tuffs cut through in places by dikes and the 
volcanic necks of centers of effusion. These flows incHne toward 
the valley with dips varying from 6° to 15° and extend under it. 
In the valley proper these flows are covered with a series of blue 
clays interstratified with sand beds, which yield flowing artesian 
water in many wells in the lower part of the drainage area. 

The rainfall on the Conejos Mountains is heavier than in any other 
part of the region drained by the Rio Grande. At Platoro (eleva- 
tion, 9,800) the mean precipitation is upward of 23 inches and at 
Cumbres (elevation, 10,015) it is about 26 inches. A large part of 
this precipitation is snowfall, which is a natural storage until May 
and June when its melting causes the high water. The precipita- 
tion rapidly decreases with the altitude, falling to about 8 inches iii 
the valley section of the drainage. 

The waters of the Conejos are extensively utihzed for irrigatior' 
in the valley, there being adjudicated decrees for appropriations of 
3,476 second-feet by direct diversion. This amount is equal to the 
entire flow of the river during the height of the flood period.

GAGING STATION RECORDS. 
CONEJOS RIVER NEAR MOGOTE, COLO. 

Location. — At highway bridge near Mogote. 

Records available. — From September 1, 1899, to March 31, 1900, and from April 17, 
1903, to October 31, 1905, at a station about 4 miles above Mogote; April 22 to June 
21, 1906, and March 21, 1907, to October 5, 1911, at Jacob's ranch, 8 miles above 
Mogote. January 1, 1912, to September 30, 1913, at present site. 

Drainage area. — Not measured. 

Gage. — Staff gage, originally located at wagon bridge at Conejos, but moved to a 
point 500 feet below on November 5, 1899. The datum of the gage remained per- 
manent as long as used. At the station established in 1907 a chain gage was used, 
referred to the same datum as a rod gage used by Mr. Antoine Jacob during 1905 
and 1906. This datum remained unchanged until the station was changed in 
1911. 

Channel. — Fairly permanent at present site but shifting at original site. 

Discharge measurements. — Made from bridge. 

Winter flow. — Ice causes backwater during the winter months. 

Diversions. — There are court decrees for diversions of 3,476 second-feet from Conejos 
River, all but about 66 second-feet being diverted below the present station. 

Accuracy. — Data prior to 1903 too meager to permit estimates of daily discharge 
being made. From 1903 to 1905 conditions were favorable for estimates, which 
are considered fair; the estimates since 1907 are considered good and for some 
months even excellent. 

Cooperation. — During 1912 and 1913 station was maintained by the State engineer, 
who furnished the complete records.

Note.— Estimate for December, 1907, revised since being published originally. Daily discharge esti- 
mated November 23 to 30, 1908. Estimates for January, February, and March 1-8, 1910, are based on two 
discharge measurements made during that period. Estimates for December, 1910, and January, February, 
and March 1-11, 1911, are based on three discharge measurements made during that period. Estimates for 
January, February, and March, 1912, are based on two discharge measurements made during that period. 
The State engineer of Colorado estimated the discharge for January, February, and March, 1913, at 43 
econd-feet, 44 second-feet, and 56 second-feet, respectively. 



RIO SAN ANTONIO NEAR ORTIZ, COLO. 

Location. — At the lower San Antonio ranger station in the Carson National Forest, 
in sec. 1, T. 30 N., R. 7 E.; nearest tributary a small stream entering from the 
south just above the station; Nutritus Creek enters 2 miles above. 

Records available. — June 16, 1911, to November 27, 1911. 

Drainage area. — Not measured. 

Gage. — Vertical staff. 

Channel. — Data too meager to determine. 

Discharge measurements. — Made by wading. 

Winter flow. — Ice causes backwater during the winter months and the records are 
discontinued. 

Diversions. — Four small diversions above the station. 

Accuracy. — Owing to lack of discharge measurements, estimates of flow can not be 
made. 

Cooperation. — Station maintained in cooperation with the United States Forest 
Service. 

The following discharge measurement was made by H. B. Waha: 
June 16, 1911: Gage height, 1.10 feet; discharge, 8.5 second-feet.

COSTILLA CREEK BASIN. 



GENERAL FEATURES. 



Costilla Creek rises on the western slope of the Sangre de Cristo 
Range Gocally known as the Costilla Mountain) in the Sangre de 
Cristo grant, Taos County, N. Mex,; it first flows southward, then, 
making a sharp turn, flows northwest, entering Colorado near Cos- 
tilla; at Eastdale it turns to the southwest, again crosses into New 
Mexico, and joins the Rio Grande a few miles south of the Colorado- 
New Mexico line. It has no important tributaries and sends no 
water to the Rio Grande except during the spring high stage and 
after heavy rains. 

The upper part of the drainage area comprises the western slope of 
the Sangre de Cristo Mountains from which the greater part of the 
water supply is derived. The lower and by far greater part of the 
area is included in the Cerro Mesa, a smooth tract of land at a general 
elevation of 8,000 feet above sea level. 

Precipitation in the Costilla basin decreases from 23 inches or more 
at the crest of the Sangre de Cristo Mountains to 13 inches or less at 
the mouth.

378 WATER EESOUKCES OF RIO GRANDE BASIN, 1888-1913. 

RIO COLORADO' BASIN. 
GENERAL FEATURES. 

Rio Colorado drains an area lying on the western slope of the Sangre 
de Cristo Mountains in northern New Mexico. It rises in the south- 
eastern corner of T. 28 N., R. 14 E., at an elevation of nearly 10,000 
feet above sea level, flows north for a distance of 6 miles, then turns 
and flows in a general westerly course to its junction with the Rio 
Grande, in sec. 17, T. 28 N., R. 12 E. Its principal tributaries are 
Bitter and Cabresto creeks from the north and Goose, Placer, Pioneer, 
and Columbine creeks from the south. 

Above Questa the country is mountainous, with elevations ranging 
from 8,000 feet at Questa to more than 10,000 feet at the divide. In 
this section the tributaries flow through narrow valleys, though the 
valley of the Colorado itself has gently sloping sides. Below Questa 
and north of the river the basm includes the southern end of a large 
smooth mesa known as Cerro Mesa, but south of the Colorado the 
surface is more broken. 

The mean annual precipitation in the upper part of the drainage 
basin, on the western slope of the mountain range, is 24 inches or 
more; at the mouth of the river, on the mesa, it is about 13 inches. 

W. W. Follett, in his report on the ''Distribution of waters of the 
Rio Grande," states that irrigation is carried on extensively in the 
southern portion of the Cerro Mesa, in the vicinity of Questa. There 
are no reservoirs in operation in the basin of the Rio Colorado. 

GAGING STATION RECORDS 
RIO COLORADO ABOVE QUESTA, N. MEX. 

Location. — Five miles above Questa, in Taos County, and about 5 miles above Cabresto 

Creek, the nearest tributary, near sec. 2, T. 28 N., R. 13 E. 
Records available. — April 5, 1910, to September 4, 1911, when the station was 

discontinued. 
Drainage area. — Not measured. 
Gage. — Vertical staff; table of gage heights for 1910 refer to a gage at a different 

datum and location. 
Channel. — Apparently permanent. 
Discharge measurements. — Made by wading. 
Winter flow. — No information available. 
Diversions. — No data. 
Accuracy.— Owing to the small number of gage heights, satisfactory estimates can 

not be made. 
Cooperation. — Station maintained in cooperation with the United States Forest 

Service and the State engineer.

WATER EESOURCES OF EIO GRANDE BASIN, 1888-1913. 



EIO COLORADO BELOW QUESTA, N. MEX. 

Location. — Two miles below Questa, at the head of Lower Canyon, near sec. 1, T. 
28 N., R. 12 E., below all important tributaries, the nearest one above being 
Cabresto Creek. 

Records available. — April 8, 1910, to September 30, 1913. 

Drainage area. — Not measured. 

Gage. — Vertical staff. 

Channel. — Shifting during high water. 

Discharge measurements. — Made by wading or from car and cable, 

Winter flovr. — Slightly affected by ice during December and January of each year. 

Diversions. — There are no diversions below, but, for several miles above, diversions 
are made for irrigation. 

Accuracy. — Owing to radical changes in the stream bed, estimates of discharge were 
not made in 1910 and 1911. The estimates made during the first part of 1912 can 
not be considered better than fair, but those thereafter can be rated as good. 

Cooperation. — Station maintained in cooperation with the United States Reclama- 
tion Service and the State engineer.

386 WATER KESOUECES OF RIO GRANDE BASIN, 1888-1913. 

RIO HONDO BASIN. 
GENERAL FEATURES. 

Rio Hondo, one of the comparatively few perennial tributaries of the 
Rio Grande, rises near the crest of the Taos Mountains — the southern 
extension of the Sangre de Cristo Range — and takes a general 
westerly course to its junction with the Rio Grande about sec. 31, 
T. 27 N., R. 12 E. Its chief tributaries are Long Canyon, Lake Creek, 
South Fork, and Turkey Creek. 

The drainage of the Rio Hondo is mountainous for the most part. 
The Hondo reaches 10,000 feet, while of its tributaries Long Canyon 
nearly reaches 11,000, Lake Fork 12,000, and the South Fork 10,000 
feet, insuring a supply of water from the snows of the higher moun- 
tains. In the lower half of the area the altitude ranges between 
8,000 and 9,000 feet. 

No records have been taken within the Rio Hondo basin, but from 
records of neighboring areas it is probable that the mean annual pre- 
cipitation for the lower portion of the basin is between 14 and 15 inches, 
while in the upper portion it may reach 24 inches, owing to the 
greater altitude. 

In FoUett's report on the "Distribution of the waters of the Rio 
Grande" it was stated that prior to 1896 there were six irrigation 
ditches having a total capacity of 69 second-feet taking water from 
the Rio Hondo for irrigation in the valley below Cristone. 

GAGING STATION RECORDS. 
RIO HONDO NEAR ARROYO HONDO, N. MEX. 

liocation. — At highway bridge at Dunn's ranch, 200 yards above the mouth of the 
stream, 1 mile west of Arroyo Hondo post office, near sec. 31, T. 27 N., R. 12 E. 
No tributary between station and mouth. 

Records available. — April 8, 1910, to September 30, 1913. 

Drainage area. — Not measured. 

Gage. — Inclined staff. 

Channel. — Shifting. 

Discharge measurements. — Made by wading at low stages and from a bridge at 
high stages. 

Winter flow. — Ice causes slight backwater during portions of the winter months. 

Diversions. — None below, but several diversions for irrigation are made above. 

Accuracy. — Owing to the discrepancy in the gage heights recorded by the hydrographer 
and the observer, no estimates of discharge were made in 1911 and the first part 
of 1912. The estimates for the last part of 1912 and those for 1913 are considered 



Cooperation. — Station maintained in cooperation with the United States Reclama- 
tion Service and the State engineer.

Note.— Daily discharge determined from two fairly well defined rating curves and by the indirect method 
for shirting channels. Discharge estimated Jan. 1 to Feb. 28, 1913, on account of ice. Discharge interpo- 
lated for other days for which gage heights are missing. Stream dry Jan. 1 to Feb. 4 and Feb. 12-21, 1912

390 WATER EESOUECES OF EIO GEANDE BASIN, 1888-1913. 

RIO TAOS BASIN. 
GENERAL FEATURES. 

Rio Taos is formed by the junction of the Rio Pueblo, Rio Fer- 
nando, and Rio Grande del Rancho near Los Cordovas, a few miles 
west of Taos. The headwater streams rise on the western slope of 
the southern extension of the Sangre de Cristo range, known locally 
as the Taos Mountains. The general course of the streams is west- 
ward, and below the junction Rio Taos flows southwestward, joining 
the Rio Grande about 7 miles below the junction. The chief tribu- 
tary of Rio Pueblo is Rio Lucero. Rio Fernando has no important 
tributary. The principal tributaries of the Rio Grande del Rancho 
are Rio Chiquito and Arroyo Miranda. 

Above the junction of the principal headwater streams the area is 
mountainous, elevations ranging between 7,000 and 10,000 feet or 
higher, and the streams flow in canyons. Below the junction Rio 
Taos crosses a level mesa, which is 7,000 feet in altitude and is known 
as Taos Valley. 

At the crest of the mountains the mean annual precipitation is 24 
inches or more, but it decreases rapidly with decrease in altitude, 
being only about 14 mches at Taos and throughout the lower part of 
the basin. The precipitation in the mountains is largely in the form 
of snow, which is the chief source of supply of the stream. 

In his report on the Rio Grande, issued in 1896, W. W. Follett 
states that the area of irrigable land in Taos Valley is fully 40,000 
acres, but that the water supply is only sufiicient for about half this 
land, and it has been utihzed for the last 50 years or more. At the 
time the report was issued it was estimated that ditches having a 
total capacity of 316 second-feet diverted water from Rio Taos and 
its tributaries. 

GAGING STATION RECORDS. 

RIO PUEBLO DE TAOS NEAR TAOS, N. MEX. 

Location. — Two miles above Taos Pueblo, 4J miles northeast of Taos, at Glorietta 
Grove, near sec. 2, T. 25 N., K. 13 E. A number of intermittent tributaries 
enter above and below the station. 

Records available. — March 12, 1910, to September 30, 1913. Gage height records 
prior to December, 1910, are fragmentary and hot published. 

Drainage area. — Not measured. 

Gage. — Automatic recording. Installed by the United States Indian Service Decem- 
ber 19, 1910. A vertical staff gage was installed first, but was destroyed before 
July 12, 1910. On October 12, 1910, a new gage was installed which was referred 
to a datum 0.27 foot lower than the original. The automatic gage was referred to 
the datum of the second gage. 

Channel. — Somewhat shifting, especially during high stages. 

Discharge measurements. — Made by wading. 

Winter flow. — Ice causes backwater during the winter period. 



RIO TAOS BASIN. 



391 



Diversions. — None above this statiou, but several are made just below. 

Accuracy. — The few discharge measurements indicate that there was not much shift 
during 1911, and therefore the estimates may be considered fairly good. The esti- 
mates for 1912 are fragmentary and can only be considered fair. Those for 1913 
may be considered good. 

Cooperation. — Station maintained in cooperation with the United States Forest 
Service, United States Indian Service, and State engineer.

RIO TAOS BASTN. 



405 



RIO FERNANDO DE TAOS NEAR TAOS, N. MEX. 

Location. — Two miles southeast of Taos, 200 yards upstream from the headgate of 
B. G. Randall's intake ditch, at the mouth of the canyon, in sec. 21, T. 25 N., 
R. 13 E. 

Records available. — Fragmentary records from April 6, 1910, to September 30, 1913. 

Drainage area. — Not measured. 

Gage. — Vertical staff. Datum has remained unchanged since the date of establish- 
ment. 

Channel. — Permanent at low stages, but subject to a shift during high water. 

Discharge measurements. — Made by wading. 

Winter flow. — No ice effect during the winter months. Springs just above the 
section keep it open. 

Diversions. — No water of consequence diverted above the station. The flow at this 
point represents the natural run-off. 

Accuracy. — The estimates of discharge made in 1912 and 1913 can be considered good. 

Cooperation. — Station maintained in cooperation with the State engineer.

CHAMA RIVER BASIN. 



GENERAL FEATURES. 



Chama River rises on the western slope of the Conejos Mountains, 
a few miles north of the Colorado-New Mexico line, at an approximate 
elevation of 12,000 feet above sea level, flows in a general southerly 
course which finally becomes southeasterly, and enters the Rio 
Grande at Chamita, about 30 miles north of Santa Fe, in the Espanola 
Valley. It has a number of short tributaries, the most important 
being the Brazos, Horn, GaUinas, Cebolla, Puerco, and Caliente. 

The drainage area is bounded on the east by that of the Conejos 
River, which merges with the Black Mesa, and on the west by the 
Continental Divide. It consists chiefly of high plateaus and moun- 
tain ranges. The upper portion of the river above the mouth of the 
Brazos is in a canyon, but between the Brazos and the Nutritus the 
river flows through a low fertile mesa. Below this point it again 
flows through an ahuost continuous canyon to Abiquiu, where it 
enters the Chama Valley which continues to the mouth. 

From its mouth as far up as Gallinas Creek the Chama itself and 
all its tributaries are muddy, but above the Gallinas the water is 
somewhat clearer, especially that of the Brazos. 

All the tributaries that enter below the Cebolla, except the Puerco, 
have broad sandy channels near their mouths, and in this part of 
their courses lose much of their water by seepage and evaporation. 
The loss in the Caliente, Oso, El Rito, Lower Canyones, and Horn 
rivers is especially large.^ 

The chief source of the perennial flow of the streams is the snow 
that falls on the western slope of the Conejos Range. At Cumbres 
(elevation 10,015) on the eastern slope the annual precipitation is 
upward of 25 inches, and as the prevailing winds are from the west 



1 For seepage in the Chama itself see p. 690.

WATER RESOURCES OF RIO GRANDE BASIN, 1888-1913. 



it is probable that on the western slope the precipitation is even more. 
The only record in the upper Chama Basin is at Chama (elevation 
7;848) where the mean precipitation is 23 inches. South from the 
source the precipitation decreases, being about 15 inches at the 
mouth of the Gallinas, 13 inches at Abiquiu, and 12 inches at the 
mouth. Much of the precipitation of the lower portion of the basin 
comes in the form of violent rains which subject the river to sudden 
floods. 

Irrigation is carried on extensively in the valleys bordering the 
Chama and some of its tributaries. FoUett, in his report on the 
"Distribution of the waters of the Rio Grande," states that prior to 
1896 there were ditches having a total capacity of 1,141 second-feet 
diverting water from the Chama and its tributaries, of which 352 
second-feet was the total capacity of ditches diverting water from 
the Chama itself. 

GAGING STATION RECORDS. 



CHAMA RIVER AT CHAMA, N. MEX. 

Location. — At the Denver & Rio Grande Railroad bridge, about half a mile northeast 
of Chama, 2 miles above the mouth of Little Chama River, in see. 13, T. 31 N., 
R. 3 E. 

Records available. — September 23, 1912, to September 30, 1913. 

Drainage area. — Not measured. 

Gage. — Vertical staff. 

Channel. — Permanent at low stages, but subject to a shift during flood stages. 

Discharge measurements. — Wading at low stages and from a bridge during flood 
stages. 

Winter flow. — Ice effect during the winter months. 

Diversions. — Very little water is taken out for irrigation above this point; conse- 
quently the discharge at this point approximates the natural run-off. 

Accuracy. — The estimates can be considered good. 

Cooperation. — Maintained in cooperation with the Tierra Amarilla Land Grant Co., 
Chama, N. Mex., and the State engineer.

Note.— Daily discharge determined from two curves well defined between 2 second-feet and 700 second- 
feet. Discharge estimated Dec. 6-31, 1912, and Mar. 1-16, 1913, on account of ice. Discharge interpolated 
on days of missing gage heights except May 10-18, June 2-12, and June 14-24, 1913, which periods were esti- 
mated from information furnished by the gage reader and hydrographer.

424 WATEE EESOUECES OF EIO GEANDE BASIN, 1888-1913. 

SANTA FE CREEK BASIN. 
GENERAL FEATURES. 

Santa Fe Creek rises near the crest of the Taos Mountains, near 
Lake Peak, 13 miles northeast of Santa Fe, at an elevation of 11,500 
feet. In its upper course it occupies a very narrow valley, but on 
leaving the foothills, 4 miles east of Santa Fe, it flows in a shallow 
channel through a level plain for 15 miles; it then enters a canyon 
through which it flows for about 6 miles and in which it falls 500 feet. 
Below the canyon, which ends at La Bajada, its course is again 
across a fairly level vaUey in which its channel is shallow. It enters 
the Rio Grande about 2 miles north of Pena Blanca. The creek 
receives no important tributaries. 

Above Santa Fe the drainage area comprises the western slope of 
the Taos Mountains where the elevations range between 7,000 and 
12,000 feet. The lower portion of the basin consists of a fairly level 
plain sloping gently toward the Rio Grande. 

The lines of equal precipitation for the Taos Mountains (PL III) 
show that the upper portion of the drainage has about 14 inches 
precipitation at Santa Fe, which increases probably to 24 inches or 
more at the source — much of this latter precipitation is in the form 
of snow, which remains during the winter months. Below Santa Fe 
the mean annual precipitation is about 13 inches, which occurs 
chiefly during the summer months. 

In 1896 W. W. Follett, in his report on the "Distribution of the 
waters of the Rio Grande," stated that — 

For a great many years the full flow of Santa Fe Creek has been utilized for irri- 
gation (below Santa Fe) and the scanty amount of water available has been husbanded 
with great care and made to serve as much land as possible. The water is alternated 
among the different ditches and the amount carried annually by each ditch on the 
main stream is said to be equal, in ordinary years, to the full capacity of the ditch 
flowing 40 days. 

The total capacity of the ditches diverting from Santa Fe Creek and 
its tributaries is given in the same report as 117 second-feet. 

The flow of Santa Fe Creek is equalized to a certain extent by a 
reservoir of 4,000 acre-feet capacity located above Santa Fe. This 
enables much of the flood water to be utilized for irrigation which 
would otherwise flow to the Rio Grande. Largely on account of the 
reservoir and of the extensive irrigation only flood water now reaches 
the Rio Grande.

GAGING STATION RECORDS. 
SANTA FE CREEK AT MONUMENT ROCK, NEAR SANTA FE, N. MEX. 

Location. — At Monument rock, a large conspicuous bowlder, 7 miles above Santa Fe, 
in sec. 30, T. 17 N., R. 11 E. No tributaries within several miles of the station. 
From June 1, 1907, to July 16, 1910, and March 8 to November 12, 1911, a station 
was maintained at Santa Fe. Between the two stations there are no important 
tributaries, but the Santa Fe \\'ater & Light Co. diverts water. 

Records available. — August 29, 1910, to August 7, 1911. 

Drainage area.^ — Not measured 

Gage. — Vertical staff. 

Channel. — Somewhat shifting. 

Discharge measurements. — Made by wading. 

Winter flo'W. — Ice causes backwater during the winter months. 

Diversions. — Little or no water is diverted above the station, and therefore the 
records represent closely the natural run-off. 

Accuracy. — Owing to the meager data no estimates of discharge are made for 1911. 
Estimates for 1910 fair.

Location. — Five miles east of Santa Fe, IJ miles above reservoir, one-fourth mile 
above Santa Fe Water & Light Co.'s diversion for water supply, in see. 22, T. 
17 N., R. 10 E. 

Records available.— April 24, 1913, to September 30, 1913. From May 12, 1910, to 
February 23, 1913, fragmentary readings were taken from a staff gage 1 mile below 
the present site and below the diversion of the Santa Fe Water & Light Co. 
From February 24 to April 23, 1913, an automatic gage was used at the old site. 

Drainage area. — 22-| square miles (measured from topographic map). 

Gage. — Automatic recording. 

Channel. — Shifting. 

Winter flow. — Backwater from ice during winter months. 

Diversions. — No diversions above the station. Records show natural run-off. 

Accuracy. — Estimates of discharge can be considered good. Estimates from Jan- 
uary 1 to April 24, 1913, have been corrected to represent the flow at the 
present station. 

Cooperation. — Maintained in cooperation with the State engineer of New Mexico.

August 22, 1908, but it remained permanent after that time. 
Channel. — Shifting. 

Discharge measurements.^ — Made from bridge and by wading. 
Winter flow. — Ice causes backwater during the winter months.

WATER EESOUECES OP EIO GEANDE BASIN, 1888-1913. 



Diversions." — Water is diverted for the Santa Fe waterworks above the station and 

several small irrigation ditches divert just above. 
Accuracy. — Owing to the lack of gage heights in 1911, no estimates of daily discharge 

have been made. Estimates for 1907 to 1910 can only be considered approximate 

on account of shifting conditions.

ARROYO HONDO NEAR SANTA FE, N. MEX. 

Location. — Six miles southeast of Santa Fe, 2,000 feet upstream from the point where 
the Santa Fe trail crosses the Arroyo Hondo, 1 mile above the confluence of the 
two branches of the Arroyo Hondo, in NE. I sec. 17, T. 16 N., R. 10 E. 

Records available. — February 21, 1913, to September 30, 1913. 

Drainage area. — 13.5 square miles. (Measured from topographic map.) 

Gage. — Automatic recording. 

Channel. — Shifting. 

Winter flow. — Ice causes backwater during the winter months. 

Diversions. — No water is diverted above this point, consequently the flow at this 
point represents the natural run-off. 

Accuracy. — Estimates of discharge can be considered only fair. 

Cooperation. — Maintained in cooperation with the State engineer of New Mexico.

RIO PUERCO BASIN. 



GENERAL FEATURES. 



The area drained by the Kio Puerco Hes west of the Eio Grande 
between the basin of the Jemez on the north and the Salado on the 
south. Rio Puerco rises on the western slope of the Jemez Mountains 
in the northern part of Sandoval County and flows in a general 
southerly direction to its junction with the Rio Grande at La Joya 
in the Belen Valley. Aside from the violent storms which furnish 
the waters lor the sudden floods to which the river is subject, almost 
the entire water supply is received from the Jemez Mountains. The 
only tributary of importance is San Jose River, known in its upper 
portion as Bluewater Creek, which during the spring has considerable 
flow. The soil over which the Puerco flows is so porous that except 
at times of violent storms there is no flow at the mouth, and therefore 
the Rio Puerco is only a flood-water tributary of the Rio Grande. 
During flood a great amount of silt is carried in the river. FoUett, 



438 WATER RESOURCES OP RIO GRANDE BASIN, 1888-1913, 

in his report on the Rio Grande, states that this may reach as high as 
15 per cent. 

The surface of the basin is much broken and comprises in the north- 
western half the barren Chama Mesa which ends at the San Mateo 
Mountains on the south. The general elevation of this mesa is 
approximately 7,000 feet. South of the San Mateo Mountains is the 
valley of the San Jose or Bluewater Creek. This stream rises in the 
Zuni Mountains on the Continental Divide, leaves them near Blue- 
water, and flows through a valley having a rich alluvial soil washed 
down' from the mountains. The valley of the Puerco itself is also 
alluvial and has been formed in the same way. At the mouth of 
of the Puerco the elevation is about 4,700 feet, indicating a compara- 
tively heavy fall throughout the course of the river. 

The lines of equal precipitation on the map (PI. Ill) indicate that 
for the portion of New Mexico adjacent to the Puerco drainage the 
mean precipitation is about 14 inches for the northern and western 
edges of this area, except on the crest of the Jemez Mountains, which 
rise some 2,000 feet or more above the general mesa level. Although 
no records are available, it is probable that precipitation is somewhat 
greater at the higher altitudes than on the mesa^ and it decreases to 
approximately 10 inches at the mouth of the river. Little of this 
precipitation is in the form of snow ; it occurs chiefly as violent storms 
which may produce severe floods. Within the boundaries of the basin 
there are many areas of considerable size which do not send surface 
streams to the Puerco or its tributaries owing to their broken topog- 
graphy and porous soil. These areas are too small and indefinite 
to be shown on the map with the large nonproducing areas. 

The alluvial valleys of the Puerco, San Jose, and their tributaries 
are irrigated as extensively as the smaU water supply will permit. 
In his Rio Grande report Follett states that prior to 1896 there were 
ditches having a combined capacity of 580 second-feet diverting 
water from the Puerco and its tributaries. 

A storage reservoir with a capacity of 20,000 acre-feet, which can 
be increased to 70,000, has been built on Bluewater Creek in T. 12 N., 
R. 12 W., for irrigation, but the water supply at this point is so small 
that the effect of the reservoir on the flow of the Bluewater is small. 

GAGING STATION RECORDS.

Location. — At the Atchison, Topeka & Santa Fe Railway bridge between Dalies 
and Rio Puerco, in sec. 31, T. 7 N., R. 1 W. Nearest tributary a small stream 
entering from the west just below. San Jose River enters about 8 miles above. 

Records available. — Fragmentary records September 7, 1910, to October 2, 1911, 
and August 19, 1912, to September 30, 1913.

Drainage area. — Not measured. 

Gage. — Staff gage. Previous to 1913 an automatic recording gage was used, referred 

to the same datum. 
Channel. — Shifting. 
Discharge measurements. — Made by wading during low stages and from car and 

cable during flood stages. 
Diversions. — No data. 
Accuracy. — Owing to meager data, no estimates of discharge have been made prior to 

1913, and those can only be considered fair. 
Cooperation. — Station maintained in cooperation with the State engineer.

452 WATER EESOUECES OF EIO GEANDE BASIN, 1888-1913. 

PECOS RIVER BASIN. 
GENERAL FEATURES. 

Pecos River, one of the most important tributaries of the lower Rio 
Grande, drains an area comprismg approximately 32,000 square 
miles and extending from the Taos Mountains in northern New Mex- 
ico to the southern edge of the western panhandle region in Texas. 
Its source is on the eastern slope of the Santa Fe Range in the extreme 
western corner of Mora County, at an elevation of 11,000 feet, and its 
course is southward nearly to Punta Pajarita, thence southeastward 
to the southeast corner of Guadalupe County, thence southward 
again to Carlsbad, and then once more southeastward to its junction 
with the Rio Grande at Moorhead, Valverde County, Tex. Except 
for some of the upper tributaries the branches of the Pecos are inter- 
mittent, though at times they carry large floods. The chief tributa- 
ries are Rio de la Vaca, Rio Tecolote, Gallinas River, Canyon Blanco, 
Pentado Canyon, Alamo Gordo Creek, Salt Creek, Felix, Penasco, 
Seven Rivers, Delaware, Toyah, and Comanche creeks. Below Fort 
Sumner there are no important tributaries from the east, as the 
boundary of effective surface drainage of the Pecos parallels the river 
at a distance of 50 miles. The few streams in this section rise in the 
edge of the high plains but lose their waters in the porous soil within 
a few miles. Many of the streams in the western portion of the basm 
sink before reaching the Pecos, and it is probable that the streams 
actually reaching the Pecos lose much water by seepage after leaving 
the mountains. 

The upper Pecos flows through narrow valleys and deeply cut 
gorges nearly down to Fort Sumner, and in this portion of the basin 
the elevations range from 4,500 feet to 11,000 feet above sea level. 
Below Fort Sumner the canyon-like walls of the Pecos are replaced 
by low rolling hills and at Roswell the gradation from the flood plains 
to the rolling prairie of the lower part of the drainage basin is imper- 
ceptible. Arroyos and gulches are rare, and canyons are practically 
unknown. Elevations in the lower section of the basm range from 
1,000 feet at the mouth to 4,500 feet near the foothills. 

The distribution of precipitation throughout the Pecos basin is 
somewhat peculiar. Near the source of the river there is a very small 
area in which the mean annual precipitation is 20 mches or more, but, 
as shown on the map (PI. Ill), the rate drops to 15 inches at Anton 
Chico and less than 13 inches at Santa Rosa. From this point to 
Carlsbad there is a narrow strip coinciding practically with the imme- 
diate valley of the Pecos where the precipitation is between 12 and 
13 inches, and east and west of this narrow area it increases to 15 inches 
or more. Below Carlsbad the increase is fairly uniform to 19 inches 
at the mouth. Except on the mountains in the upper section of the 



PECOS RIVER BASIN. 453 

basin, where much of it occurs as snow, by far the greater part of the 
precipitation is the rain of the summer storms. 

The Carlsbad project of the United States Reclamation Service irri- 
gates about 20,000 acres in the vicinity of Carlsbad. The irrigation 
plan provides for the storage of water in Lake McMillan on the Pecos 
near Lakewood, and in a storage and distributing reservoir on the 
same river near Carlsbad, controlled by the Avalon dam, and the 
diversion of water from the Avalon reservoir into a canal system 
watering lands on both sides in the vicinity of Carlsbad. The two 
reservoirs have a combined capacity of 72,000 acre-feet, thus exerting 
a marked effect on the flow of the Pecos below Carlsbad. 

Irrigation is also extensively carried on in other sections of the 
Pecos Valley, especially in the vicinity of Pecos, Tex. 

THE PECOS FLOOD OF 1904.^ 

Late in September, 1904 — chiefly on the 28th and 29th — a remark- 
ably heavy rainfall occurred in the northern part of the eastern half 
of New Mexico and in an area about 125 miles long and 50 miles wide 
lying just west of Roswell. Arabella and Hot Springs, N. Mex., seemed 
to be the two centers of the greatest precipitation in the Pecos Valley 
basin. An observer near the headwaters of Pecos River says: 

Between the 26th and 30th of September, 1904, very heavy steady rains fell over 
nearly the entire Ten-itory. The greatest damage occurred on Thursday morning, 
September 29, over the eastern slopes of the mountaijis and along the valleys and 
lowlands of the northern portion, but the floods were nearly as destructive over the 
eastern slope of the several moimtain ranges in the southwest portion and over the 
Hondo in the southeast. In an area 500 by 300 mUes reports show that a rainfall of 
3 to 7 inches fell within the space of 24 to 48 hours. 

The flood waters reached Roswell, N. Mex., on September 29, and 
in the evening of that day the water broke over the banks of the Hondo 
at 8 p. m., and in 15 mniutes the main street of that city was under 
water and the dike erected for the protection of the city swept away, 
Ukewise the railroad bridge north of the city. The flood at this place 
lasted only four days, but lines of communications were so damaged 
that no mail was delivered until October 10. The opera house and 
about 15 dwellings were destroyed. 

The crest of the flood reached Carlsbad, N. Mex., at 3 a. m. October 
2. The irrigation works were badly damaged, the cotton gin and all 
bridges on Pecos River were swept away, and the railway track for 
miles up and down the river was submerged. 

On October 3 the water reached a height of 9 feet on the United 
States Geological Survey gage 6 miles above Pecos, N. Mex., and it 
continued to rise slowly for about 48 hours. This rise was so gradual 
that it could scarcely be noted from hour to hour. At 10 p. m. on 
October 4 it began to rise on the gage at the rate of about 1 foot an

hour, and about this time four leaks occurred in the levees of the 
Barstow Irrigation Co., 3^ miles above the flume, on the west side of 
the river, which were built to protect the West Valley [system from 
flood waters. This water soon entered the canals, and by 3 a, m. 
October 5 the canals were filled and soon overflowed so rapidly that 
many breaks were made in the West Valley canals. Daybreak of 
October 5 showed a sluggish flood of murky red and gray spread from 
half a mile to 2 J miles in width on either side of the river. The cur- 
rent in the main channel of the river did not seem as boisterous as on 
the previous days, but at many points along the river currents were 
running out over the banks into and through the surrounding flats, 
covering the whole country to the foothills from 2 to 4 feet deep. At 
8 a. m., with 19 feet by gage, the flume gave two little snaps, its center 
bowed downstream, the ends tore loose, the flume slowly rose, emptied 
its water, broke in two, and the two hulks floated downstream. These 
two parts, each about 100 feet in length, finally grounded, one about 
1| miles below the flume and the other at a point about 5 miles below 
where it had caught on the banks of the river and formed a perfect 
bridge across the river channel. This section of the flume held this 
position till the gage read 10.50, but on the night of October 12 a 
small rise raised the water on the gage to 14, and in the meantime 
drift had caught above this part of the flume, and the added force 
carried the broken flume on down the river to the highway bridge 
east of Pecos City, where it passed under in some almost miraculous 
manner and caught against the railroad bridge a few hundred feet 
below. It was soon wrecked sufficiently to allow it to pass under 
this bridge. It may be remarked here that these two bridges (about 
1 mile east of Pecos City) were the only structures that remained 
across Pecos River during the flood. This was due to the fact that 
at high water a large portion of the flood waters (perhaps half) flow 
out on the east side of the river channel and through a quarter-mile 
trestle work on the Texas & Pacific Railway. 

On October 15 the gage at the flume read 9 feet, thus showing that 
the flood that swept through Roswell, N". Mex., in about three days 
had spread out enough to make some 10 days of extremely high water 
near Pecos. About October 20 most of the outlaying water had 
drained back and it had left a deposit of reddish clay and fine sand 
where the water was sluggish and coarse sand where the water was 
swift. The depth of this deposit varied from 0.20 to 0.40 feet, except 
at certain isolated points where a deposit of over 1 foot was left. 

Above the main canal of the Barstow Irrigation Co., on the 
east side of the river, the water reached a depth of 4 feet, and it 
required a period of two weeks to drain this water off. 

After the flume went out on October 5 the water level dropped 
about 0.30 foot, showing that the flume had little effect on holding

the water back. On tlie west side of the river two-thirds of the alfalfa 
was killed by the flood and about 50 per cent of the cotton was lost. 
Out of 900 acres 700 were flooded. On the east side some thousand 
acres were heavily flooded and as much more lightly flooded. The 
sorghum was injured very slightly, but from 25 to 50 per cent of the 
cotton heavily flooded was lost. Very few of the plants were killed, 
but the bolls were so soaked that they soured and were ruined. 

This flood did its greatest damage at its beginning in New Mexico, 
and the damage became less as it approached the Rio Grande. The 
flood was caused by concentrated floods in two localities in New 
Mexico. Below Carlsbad the rainfall was moderate, and it decreased 
in intensity to the south. 

GAGING STATION RECORDS. 



PECOS RIVER NEAR COWLES, N. MEX. 

Location. — At highway bridge about sec. 28, T. 18 N., R. 12 E., three-fourths of a 
mile below the old Cowles post office, 5 miles below the present Cowles post office, 
which is at Windsor, midway between the Espiritu Santo and Mora Creeks, about 
half a mile below the mouth of Willow Creek. 

Records available.— March 9, 1910, to September 30, 1913. 

Drainage area. — Not measured. 

Gage. — Automatic recording. A gage of the Bristol type was installed June 5, 1912, 
in place of a Friez automatic gage. On April 9, 1913, the Bristol gage was removed 
and on April 18, 1913, a Friez gage was reinstalled. These gages were all referred 
to the same datum. 

Channel. — Fairly permanent except dining high water, when it may shift slightly. 

Discharge measurements. — Made from bridge during high water and by wading 
at ordinary stages. 

Winter flow. — Ice causes back water during a portion of the winter months. 

Accuracy. — Conditions are favorable for accurate results and the record should be 
reliable. The estimates can be considered good, but on account of doubtful gage 
heights estimates were not made from August to December, 1912. 

Cooperation. — Maintained in cooperation with Mr. E. H. Fisher, Albuquerque, 
N. Mex., and the State engineer.

PECOS RIVER AT SANTA ROSA, N. MEX. 

Location. — Originally established at the Chicago, Rock Island & Pacific Railway 
bridge at Santa Rosa. When the station was reestablished in 1910 it was moved 
about 400 feet downstream to the highway bridge, 1 mile above the mouth of Rio 
Agua Negra Chiquita, in sec. 11, T. 8 N., R. 21 E. 

Records available.— May 5, 1903, to December 31, 1906; February 1, 1910, to July 
31, 1911; September 21, 1912, to September 30, 1913. 

Drainage area. — 2,780 miles (measured from Land Office map). 

Gage. — The original gage was a staff bolted to the bridge pier. A chain gage is used 
at the present station. 

Channel. — Very shifting. 

Discharge measurements. — At the original station, made from car and cable and 
by wading; at the present one, from the bridge and by wading. 

Winter flow. — Practically no ice at this station. 

Flood stage. — During the period covered by the records there was but one eerioua 
flood, which occurred September 29 and 30, 1904, when the river reached a 
recorded stage of 23.0 feet. 

Accuracy. — Owing to the shifting character of the stream and insufficient measure- 
ments, no estimates of discharge were made prior to 1906. Since that date esti- 
mates are available which are considered reliable. 

Cooperation. — The United States Reclamation Service maintained the station from 
1904 to 1906, but since 1910 it has been maintained in cooperation with the State 
engineer.

PECOS RIVER NEAR FORT SUMNER, N. MEX. 

Location. — At Arinosa, 4 miles northwest of Fort Sumner and 3J miles above the 
Atchison, Topeka & Santa Fe Railway bridge, in sec. 12, T. 3 N., R. 25 E. The 
nearest tributary is an arroyo entering from the west a short distance below. 

Records available.— June 12, 1904, to February 28, 1910; September 16, 1912, to 
September 30, 1913. 

Drainage area. — Approximately 5,300 square miles. 

Gage. — Original gage, a vertical staff. On July 5, 1905, an inclined staff was estab- 
lished at the present location, 1 mile downstream. The datum of the latter gage 
has remained unchanged. 

Channel. — Very shifting. 

Discharge measurements. — Prior to 1912, flood discharge was measured by floats 
and estimates from elope measurements, using Kutter's formula. Low-water 
measurements were made by wading. Since 1912 high-water measurements have 
been made from car and cable. 

Winter fl.ow. — Slush ice sometimes forms at the station and thin ice forms along the 
edges of the river, but results are not greatly affected by ice. 

Accuracy. — Owing to the very shifting channel, the estimates can only be considered 
approximate except those for 1910, 1912, and 1913, which are fair. 

Cooperation. — During 1912 and 1913, station maintained in cooperation with the 
State engineer.

PECOS RIVER NEAR ROSWELL, N. MEX. 

Location. — At highway bridge, 8 miles southeast of Roswell. Hondo River enters 

200 feet above. 
Records avaUable.— April 23, 1903, to June 30, 1906. 
Drainage area. — Not measured. 
Gage. — Original gage painted on pier of bridge. Standard chain gage used after 

September 15, 1905. It is not known whether both gages refer to the same datum. 
Channel. — Shifting after each flood. 
Discharge measurements. — Made from the bridge. Extreme flood discharge 

determined from slope, using Kutter's formula. 
Accuracy. — Prior to 1906 it was not possible to make estimates of daily discharge, 

owing to the shifting channel conditions. Estimates were made for 1906, which 

are considered reliable.

Note. — Values are rated as good. 

PECOS RIVER NEAR DAYTON, N. MEX. 

Location. — Three miles east of Dayton, in T. 18 S., R. 26 E., half a mile above the 
mouth of Penasco River. 

Records available.— March 24, 1905, to September 30, 1913. 

Drainag-e area. — Not measured. 

Gage. — Vertical staff. The original gage, which was located 100 feet below the mouth 
of the Penasco River, was washed out September 6, 1905, and was relocated Sep- 
tember 7, 1905, half a mile upstream. Datum unchanged since then. 

Channel. — Shifting during high water. 

Discharge measurements.- — Made from car and cable. 

Winter flow. — Ice has little effect on the relation of gage height to discharge. 

Diversions. — The station is about 10 miles above the dam at the outlet of Lake 
McMillan, one of the reservoirs in the United States Reclamation Service Carlsbad 
project, which irrigates about 20,000 acres in the vicinity of Carlsbad. 

Accuracy. — Owing to the shifting character of the stream, the estimates can not be 
considered in general better than fair. Those for 1912 and 1913 are, however, good. 

Cooperation. — Since 1908 station maintained by the United States Reclamation 
Service, which furnished the field data.

Note. — Discharges prior to Sept., 1905, include the flow of the Penasco. 



PECOS KIVER BASTN. 



501 



PECOS RIVER NEAR I.AKEWOOD, N. MEX. 

Location. — Three miles southeast of Lakewood, half a mUe below the McMillan reser- 
voir dam, in sec. 11, T. 20 S., R. 26 E.; no tributary between the .station and the 
reservoir; Seven Rivers enters 3 miles below. 

Records available. — January 11, 1906, to December 16, 1911, when the station was 
discontinued. 

Drainage area. — Not measured. 

Gage. — Inclined staff. The original gage was at the lower side of the dam, but was 
moved to a point near the lower end of the outlet canal February 8, 1906. On 
May 8, 1906, it was moved to its final location. 

Channel. — Shifting. 

Discharge measurements. — Made from car and cable a quarter of a mile above the 
railway bridge of the Eastern Railway of New Mexico. 

Winter flow. — Not affected by ice. 

Diversions. — Lake ^IcMillan is the upper reservoir in the Carlsbad project of the 
United States Reclamation Service. Although the flow from the lake passes the 
station, the flow over the flood spillways reaches the river below the station and 
is not recorded. 

Accuracy. — Although the channel is shifting, sufficient discharge measurements were 
made to allow estimates of discharge, ha\'ing a fair degree of accuracy, to be made 
from 1906 to 1909. No estimates were made for 1910 and 1911. 

Cooperation. — Station maintained by the United States Reclamation Service, which 
furnished the field data. 

Discharge measurements of Pecos River near Lakewood, N. Mex., in 1906-1910.

a No records of spillage for the years 1896, 1897, and 1898 were feept, except during 1898, when 106,270 
acre-feet were spilled at Lake Avalon. 

b Gates closed at McMillan and at Avalon. During month Lake McMUlan gained about 8,500 acre-feet. 

c This is water used in irrigation. No record of spillage, if any. 

d There was water either passing through gates or over spillway during March, for reservoir fell steadily, 
as did Lake McMillan.

PECOS RIVER AT CARLSBAD, N. MEX. 

Location. — At the Green Street Bridge in Carlsbad. No important tributaries within 

several miles. 
Records available.— May 28, 1903, to March 31, 1908. 
Drainage area. — Not measured. 
Gage. — Inclined staff used prior to October, 1904, when it was destroyed. A vertical 

staff gage referred to the original datum was later installed . 
Channel. — Fairly permanent except during flood stage. 
Discharge measurements. — Made from bridge during high water and by wading 

at other stages. 
Artificial control. — For storage on Pecos River, see descriptions of the Lakewood and 

Avalon stations. 
Diversions. — ^Water for irrigation is diverted extensively above the station, as it is 

located below all important diversions from the Pecos in New Mexico. 
Accuracy. — Conditions were favorable for accurate results and the estimates are con- 
sidered reliable. Owing to insufficient discharge measurements, no estimates 

were made for 1907 and 1908.

PECOS RIVER NEAR PECOS, TEX. 

Location. — At the flume of the Barstow Irrigation Co. (old Margueretta Canal Co.), 
about 6 miles above Pecos. There is no tributary within several miles. 

■Records available. — January 1, 1898, to June 30, 1907. The records at this station, 
together with those for the Margueretta flume, give the total flow of the Pecoa 
above the intake of the Barstow Irrigation Co.'s canal, except for the compara- 
tively small diversions into the West Valley ditch. 

Drainage area. — Not measured. 

Gage.— Vertical staff whose datum was lowered 1.00 foot March 22, 1906. All 1906 
and 1907 gage heights refer to the new datum. 

Channel. — Shifting. During extreme floods, such as occurred during October, 1904, 
and July, 1905, a large amount of water passes down the West Valley, west of the 
canal. This water spreads over the country from the flume to Pecos and can not 
be measured with any accuracy. 



PECOS RTVER BASIN. 



517 



Discharge measurements. — Made from car and cable 200 yards below the flume. 
Extreme flood discharge obtained from slope, using Kutter's formula. 

Diversions. — The chief diversions above the station in Texas are those of the Barstow 
Irrigation Co. and the West Valley ditch. 

Accuracy. — Owing to the shifting channel and to insufiicient discharge measurements, 
no estimates have been made for 1898; January 1 to June 30, 1901; March 20 to 
June 6, June 14 to 17, and June 24 to July 9, 1902; and October 5 to Dece mber 31, 
1904. For the remainder of the period sufficient discharge measurements were 
made to allow estimates of a fair degree of accuracy to be made.

Note. — The high-water estimates of July, 1905, can only be considered approximate, on account of the 
overflow,' which could not be measured accurately. 



MARGUERETTA FLUME NEAR PECOS, TEX. 

Location. — At the crossing of the Barstow Irrigation Co.'s canal over Pecos River, 
about 6 miles above Pecos and 3 miles below the head gates of the canal. 

Records available. — ^January 1 to December 31, 1898; January 1, 1900, to June 30, 
1907. 

Gage. — Vertical staff located at the east end of the flume, having its zero at the bottom 
of the flume. The gage was originally located at the west end of the flume, but 
as water was sometimes wasted into the river just beyond this point, the gage 
heights did not at all times represent the amount used for irrigation. For that 
reason the gage was moved to the east end November 17, 1905. 

Channel. — Shifting, due to deposits of silt at different times. 

Discharge measurements. — Made at the east end of the flume. 

Diversions. — About 10 second-feet are diverted into the West Valley ditch above the 
flume and at times water is wasted from the flume into the Pecos above the station, 
so the records subsequent to November 17, 1905, do not represent the amount of 
water actually diverted, but the amount available for irrigation below the crossing. 
Prior to that date, except for the West Valley ditch, the records represent the 
amount of water diverted. 

Accuracy. — Owing to the shifts of channel the estimates in general can not be con- 
sidered better than fair.

Note. — Discharge for 1903 determined from a curve not well defined. 

Discharge for 1904 determined from a fairly well defined curve. 

Discharge for 1905 determined from a rating curve fairly well defined between 100 and 260 second-feet. 

Discharge for 1906 determined from two rating curves, one well defined used prior to May 24, and the 
other well defined between 20 and 180 second-feet. Owing to changing conditions the discharge from 
May 2 to June 7 may be in error. Discharge for 1907 determined from three rating curves, all of them 
being approximate only.

PECOS RIVER NEAR MOORHEAD, TEX. 

Location. — Immediately above the high bridge of the Southern Pacific Railroad near 
Moorhead. No tributary between the station and the mouth. 

Records available. — May 1, 1900, to September 30, 1913. (Also gage heights for 
1898.) 

Drainage area. — Not measured. 

Gage. — Vertical staff bolted to bridge pier; read with field glasses from the top of the 
cliff. Nothing is known regarding the gage used in 1898. 

Discharge measurements. — Made from car and cable. 

Channel. — Shifting. 

Diversions. — The records at this station do not represent the natural run-off, as water 
is diverted extensively for irrigation. 

Floods. — The highest known flood occurred April 6, WOO, and reached a stage of 
35.75 feet upon the gage subsequently established. The floods of the lower Pecos 
are of a very flashy character. 

Accuracy. — Owing to the shifting channel conditions very frequent discharge meas- 
urements are made, and the estimates of daily discharge based almost entirely on 
these. 

Cooperation. — Station maintained by the United States section of the International 
Water Commission, by whom the records are furnished. 

Discharge measurements of Pecos River near Moorhead, Tex. , in 1900-1913.

GALLINAS RIVER BASIN. 



GENERAL FEATURES. 



Gallinas River, one of the most important tributaries of the upper 
Pecos, rises on the eastern slope of the Santa Fe Mountains, about 
20 miles northwest of Las Vegas, flows in a general southeasterly 
course, and enters Pecos River at La Junta, on the northern edge of 
Guadalupe County. It receives no important tributaries. 

The Gallinas flows through narrow valleys and canyons from its 
source at 9,000 feet elevation to its mouth, except in a stretch about 
10 miles long in its lower course, where it flows across a comparatively 
open valley. The entire basin is rough, the mountains of the head- 
water region giving way to mesas deeply cut by drainage lines. 
Below Las Vegas the Gallinas receives little if any drainage from the 
region to the north, as this is devoid of drainage lines and has many 
sinks. From this large noncontributing area and the almost entire 
absence of tributaries, it is evident that the chief source of the water 
supply is the Santa Fe Mountains. 

The mean annual precipitation at the headwaters of the Gallinas, 
in the Santa Fe Mountains, is 20 inches or more, and it decreases to 



PECOS RIVER BASIN. 561 

18 inches at Las Vegas and 13 inches at the mouth. Except on the 
headwaters, the precipitation occurs chiefly as rain during the summer 
months. 

In 1903 the United States Reclamation Service began the investi- 
gation of a project to irrigate 10,000 acres in the vicinity of Las 
Vegas. It was proposed to utiUze a reservoir site lying 5 miles north 
of Las ^>gas and 2 miles east of Hot Springs. The reservoir, which 
would have a capacity of 38,000 acre-feet, was to be suppUed with 
water by diverting the flood run-off from Sapello, Gallinas, San Gui- 
jucla, and Arroyo Pecos creeks. Further than making the surveys 
and maintaining records of flow, nothing has been done by the Recla- 
mation Service. 

GAGING STATION RECORDS. 
GALLINAS RIVER NEAR LAS VEGAS, N. MEX. 

Location.— At Las Vegas Hot Springs, 6 miles northwest of Las Vegas, near sec. 1, 
T. 16 N., R. 15 E. No tributaries between the station and Las Vegas nor for 
several miles above. 

Records available.— August 13, 1903, to May 31, 1912; December 1, 1912, to Sep- 
tember 30, 1913. 

Drainage area. — 89 square miles (measured from topographic sheets). 

Gage. — Vertical staff, 600 feet above the power house footbridge, installed to replace 
the original gage which was washed out September 29, 1904; datum of new gage 
0.71 foot lower than that of the original gage. 

Channel. — Somewhat shifting during high water. 

Discharge measurements. — Made from the footbridge during high water and by 
wading at ordinary stages. 

Winter flow. — Gage heights unaffected by ice, as channel is kept open by the hot 
springs. 

Diversions. — A short distance above the station is a timber dam which forms a pond 
from which ice is cut. This dam does not control the flow in any way. A small 
amount of water is diverted at this point for storage by the Agua Pura Co., which 
furnishes Las Vegas and the Santa Fe Railway ^"ith water. A mile below the 
station is a dam which diverts the flood flow of the Gallinas to the San Guijuela 
Basin. The fall of the river is so heavy that the gaging station is above the 
influence of this dam. During the last of February, 1913, the Agua Pura Co. 
began diverting water 1^ miles above the station. 

Accuracy. — Although the river is somewhat shifting at this station, it is believed that 
the estimates of discharge are reliable. 

Cooperation. — Diu"ing 1912 and 1913 station maintained in cooperation ■with the 
State engineer.

HONDO RIVER. BASIN. 



GENERAL FEATURES. 



Hondo River, one of the intermittent tributaries of the Pecos, is 
formed by the junction of the Rio Ruidoso and Bonito Creek in the 
northern part of T. 11 S., R. 17 E. It flows eastward and enters the 
Pecos 6 miles southeast of Roswell. The chief tributaries are North 
Spring and Berrendo rivers from the north, and South Spring River 
from the south. 

The basin comprises the eastern slope of the Sierra Blancas, where 
elevations reach 12,000 feet above sea level, and the southern slope of 
the Sierra Capitan, whose altitude is somewhat lower. On the head- 
waters of tributary streams there are a number of lakes which are fed 
by springs, and thus insure a perennial flow in the upper part of the 
Hondo. Farther down the water is diverted to such an extent for 
irrigation that there is no flow in the lower river except during floods. 
The river also probably loses much water by seepage through the 



PECOS EIVER BASIN. 579 

porous soil of the Pecos Valley, over wliich it flows in its lower course. 
So porous is the soil that ji iniiubcr of streams that should be tributary 
to the upper stretch of the Hondo lose their waters in the ground 
before reaching it. 

The lines of equal precipitation for the southeastern part of New 
Mexico (PI. Ill) indicate that the mean annual precipitation in the 
mountains at the upper end of the basin is approximately 23 inches. 
It rapidly decreases with the altitude, being about 16 inches at Fort 
Stanton and 12 inches at Roswell, near the mouth. The precipitation 
occurs cluefly during the summer months, although there is a light 
snowfall in -the mountains. 

Irrigation has been carried on extensively in the Hondo basin, 
especially on the headwater streams, for many years. The United 
States Reclamation Service has constructed a system, known as 
the Hondo project, wliich is designed to store the flood waters in 
Hondo reservoir, located in T. 11 S., Rs. 22 and 23 E., for use in 
irrigating 10,000 acres in the vicinity of RosweU. The reservoir has 
a capacity of 40,000 acre-feet. 

GAGING STATION RECORDS. 
HONDO RIVER AT HONDO RESERVOIR SITE, NEW MEXICO. 

Location. — Just below the diversion dam for the Hondo reservoir, in sec. 34, T. 11 S., 
R. 22 E., 12 miles southwest. of Roswell. No tributaries within several miles. 

Records available. — June 7, 1903, to December 31, 1906. 

Drainage area. — Not measured. 

Gage. — Inclined staff; datum unchanged. 

Channel. — Shifting. 

Discharge measurements. — Made from near-by footbridge. 

Diversions. — The normal flow is diverted for irrigation above the station, leaving 
only the flood flow available for storage in Hondo reservoir. 

Storage. — Hondo reservoir has a capacity of 40,000 acre-feet and is designed to store 
the flood waters of the river. As it was not completed until 1906, it is possible that 
prior to that year little, if any, water was stored during the period covered by the 
records. 

Accuracy. — Owing to the shifting channel and insufiicient measurements, estimates 
of daily or monthly discharge for years prior to 1906 have not been made. P^or 
that year the estimates can be considered only approximate.

NoTK. — Canal was dry on days for which no gage heights are published. 



HONDO RIVER AT ROSWELL, N. MEX. 

Location. — At the bridge at the intersection of Main and Vegas Streets, Roswell. 

Between Roswell and the mouth the Hondo receives North and South Spring 

rivers, which are fed by springs at their source. 
Records available.— June 8, 1903, to February 28, 1906. 
Drainage area. — Not measured. 
G-age. — Inclined staff. A new gage was set August 8, 1905, and it is not known 

whether it was referred to the original datum. This gage was lowered 3 feet 

February 8, 1906, and all gage heights for 1906 were referred to the later datum. 
Channel. — Shifting. 

Discharge measurements.^ — Made from bridge. 

Diversions. — The normal flow is diverted for irrigation above the station. 
Storage. — Hondo reservoir has a capacity of 40,000 acre-feet and is designed to store 

the flood waters of the river. As it was not completed until 1906 it is possible that 

prior to that year little if any water was stored during the period covered by the 

records. 
Accuracy. — Owing to insufiicient data, estimates of daily and monthly discharge have 

not been made for periods prior to 1906, and estimates for subsequent periods are 

only approximate.

PENASCO RIVER BASIN. 
GENERAL FEATURES. 

Penasco River, an. intermittent tributary of the Pecos, rises high 
on the eastern slope of the Sacramento Mountains and takes an east- 
erly course to the Pecos, which it enters near Dayton. The tribu- 
taries are chiefly confined, to the upper portion of the basin, except 
Bluewater Creek, which enters near the Chaves-Eddy County line. 
The principal tributaries are Elk and Chiquito creeks. 

The topography of the Penasco basin is similar to that of the 
Hondo, the upper portion including the eastern slope of the Sacra-

mento Mountains and reacliing to their crest. Throughout its upper 
course the Penasco is a perennial stream, but, owing to the porous soil 
of the Pecos VaUey, across which it flows after leaving the foothills 
of the Sacramento Mountains, the water sinks into the ground, leav- 
ing only flood water to reach the Pecos. 

The precipitation in the basin of the Penasco decreases from 23 
inches and more at the crest of the Sacramento Mountains to 21 
inches at Elk and 12 inches at the mouth. Most of the precipitation 
occurs during the summer months.

DELAWARE RIVER BASIN, 
GENERAL FEATURES. 

Delaware River rises in the northern part oi Culberson County, 
Tex., on the eastern slope of the Guadalupe Mountains, flows north- 
eastward, and joins the Pecos a few miles above the New Mexico- 
Texas Hne. The only important tributaries are the headwater 
streams forming the Delaware. 

The mean annual precipitation, as determined from the lines of 
equal rainfall (PL III) is about 13 inches for the area drained by the 
Delaware. On the headwaters, which rise at a considerably higher 
altitude, it is probable that the precipitation is somewhat greater.

DEVILS RIVER BASIN. 



GENERAL FEATTJBES. 



Devils River rises in the western part of Sutton County, Tex., and 
takes a general southerly course to its junction with the Rio Grande 
at Devils River, in the southern part of Valverde County. It has 
no important branches. Except the Pecos, it is the most important 
tributary of the lower Rio Grande that enters from the Texas side, 
and in some years, owing to the extensive diversions from the Pecos 
and the lighter rainfall on the basin of that stream, it contributes 
more run-off. 

The area drained by Devils River hes on the southern extension 
of the Great Plains region known as the Edwards Plateau — a high 
mesa or table-land sloping gently upward toward the northwest — 
unforested except for scattered dense patches of scrub live oak, and 
covered with a thick growth of grass. The predominant rock of the 
area is a rough limestone, whose surface is level, as a rule, but is cut 
deeply by the few streams. Devils River flows in canyon for much 
of its course. Owing to the general flatness of the surface, drainage 
lines are few, and much of the run-off coUects in shaUow sinks so 
that the effective drainage area of the river is uncertain. 

Records of rainfall at points within and adjacent to the basm 
show the mean annual precipitation to be about 20 inches and to 
occur chiefly during the summer months.

GAGING STATION RECORDS. 
DEVILS RIVER AT DEVILS RIVER, TEX. 

Location. — Near the mouth of Devils River and opposite the station of the same 
nuine on the Southern Pacific Railroad. 

Records available. — May 1, 1900, to September 30, 1913. 

Drainage area. — Not measured. 

Gage. — Vertical staff. 

Channel. — Rocky and rough, with fissures and faults. 

Discharge measurements. — Made from car and cable. 

Floods. — The highest recorded flood occurred April 6, 1900, reaching a stage corre- 
sponding to 25.4 feet on the gage subsequently established. The next highest 
stage was 15.25 feet, the discharge being 52,400 second-feet. 

Accuracy. — Owing to the uncertain conditions of channel, very frequent discharge 
measurements are made, on which the estimates of daily discharge are based 
almost directly. 

Cooperation. — Station is maintained and records are furnished by the United States 
section of the International Water Commission.

northeastern part of Grant County, N. Mex. It rises on the west 
slope of the Mimbres Range, in T. 14 S., R. 10 W., and flows in a south- 
erly direction until its waters are lost in the desert plain in Luna 
County. It has no important surface tributaries, as the waters of 
Whitewater Draw, Lampbright Draw, and Cameron Creek are lost a 
short distance from its channel, but it is possible that they reach the 
Mimbres by seepage. 

The upper part of the basin, which furnishes a practically perennial 
flow to the Mimbres at least as far as the gaging station near Faywood, 
lies in mountainous country between the Continental Divide and the 
Mimbres Mountains, with elevations ranging from 5,000 to 8,000 
feet above sea level. The lower part of the basin is a comparatively 
flat, gently sloping plain, in wliich elevations range from 4,200 to 
5,000 feet above sea level and above which rise isolated mountains. 
In its course across this plain the river is intermittent for many miles 
before its waters finally disappear east of Deming. 

The lines of equal rainfall for the southwestern part of New Mexico 
(PI. Ill) indicate that the mean annual precipitation in the Mmbres 
basin decreases from 17 inches or more in the upper part to 10 inches 
in the vicinity of Deming. Although there are no records of rainfall 
in the mountainous part of the area, it is probable that the precipi- 
tation at the higher altitudes exceeds 17 inches. 

Little water is used for irrigation above the gaging station near 
Faywood, but below that point much of the flow is diverted. With- 
out storage, which has not yet been provided, the possibilities of 
irrigation from the Mimbres are small, as it is chiefly a floodwater 
stream. A good dam site located near the gaging station could be 
utilized to form a reservoir that would store sufficient water to reclaim 
several thousand acres of land along the river. 

GAGING STATION RECORDS. 
MIMBRES RIVER NEAR FAYWOOD, N. MEX. 

Location. — About 6 miles northeast of Faywood Hot Springs, in sec. 7, T. 20 S., R. 

10 W., 10 miles from Faywood, a station on the Silver City branch of the Atchison, 

Topeka & Santa Fe Railway. 
Records available.— April 8, 1908, to September 30, 1913. 
Drainage area. — Approximately 450 square miles. 
Gage. — Automatic recording, installed August 13, 1909, at a point 200 feet upstream 

from the site of the chain gage originally installed. The chain-gage datum was 

lowered 4.00 feet on July 8, 1909, and the datum of the recording gage ia about 

3.00 feet higher than the new datum of the chain gage. 
Channel. — Very shifting.

WATER RESOURCES OF RIO ORANDE BASIN, 1888-1913. 



Discharge measurements.^ — Made from car and cable during high water and by 

wading at other times. 
Winter flow. — Practically no backwater from ice at this point. 
Accuracy. — Owing to the meager data and shifting channel no estimates of discharge 

were made for 1911. The estimate for the other years are either approximate or 

fair, except for the last half of 1912 and for 1913, for which they may be considered 

good . 
Cooperation. — During 1912-13 station was maintained in cooperation with the State 

engineer.

Note.— It is doubtful whether the gage heights Nov. 9 to Dec. 6, 1908, are plus or minus readings. Gage 
heights Jan. 1 to Aug. IS, 1909, refer to a datum 4 feet lower than that of the original gage. Gage heights 
thereafter refer to an automatic gage located 200 feet upstream and whose datum is about 3 feet above 
that of the second gage. Gage heights Jan. 1 to Mar. 9, 1912, were below 0.5 foot.

WATER RESOURCES OP RIO GRANDE BASIN, 1888-1913. 



WHITEWATER DRAW AT HURLEY, N, MEX. 

liocation. — ^About the center of eec. 30, T. 18 S., R. 12 W., at "B" ranch pumping 
station of the Chino Copper Co., half a mile northeast of Hurley. About 1 mile 
above the hydraulic fill dam being built by the Chino Copper Co. A small draw 
enters from the east below the station. 

Records available. — ^June 2 to September 30, 1913. 

Drainage area. — 35 square miles. (Taken from topographic sheet.) 

Gage. — Vertical staff. 

Channel. — Shifting. 

Discharge measurements. — By wading and from car and cable. 

Winter flo-w. — Very little effect from ice during the winter months. 

Flood discharge. — Creek subject to sudden floods. No flow most of the year. 

Accuracy. — Owing to a lack of discharge measurements, estimates of daily and 
monthly discharge can not be made. 

Cooperation. — Maintained in cooperation with the State engineer of New Mexico and 
the Chino Copper Co., Hurley, N. Mex. 

The following discharge measurement was made by E. L. Redding: 
August 15, 1913; gage height, 2.15 feet; discharge, 8.4 second-feet. 

Daily gage height, in feet, of Whitewater Draw at Hurley, N. Mex., for 1913.

CAMERON CREEK AT FORT BAYARD, N. MEX. 

Location. — Near the pumping plant at Fort Bayard, in sec. 25, T. 17 S., R. 13 W. 

1 mile below the mouth of the nearest tributary, Beartooth Creek, an intermittent 

stream. 
Records available. — ^January 17, 1907, to September 11, 1911; August 6, 1912, to 

September 30, 1913. 
Drainage area. — Not measured. 

Gage. — Vertical staff for high stages and inclined staff for medium and low stages. 
Channel. — Shifting . 
Discharge measurements. — Made by wading. For the greater part of the year 

the flow comes from springs and amounts to less than 1 second-foot. 
Winter flo-w. — Ice does not appreciably affect the flow at this station. 
Diversions. — The intake for the Army post water supply is above the station, and a 

small amount of water is also diverted for garden irrigation. 
Accuracy. — Owing to the shifting character of the stream and a lack of high-water 

discharge measurements, estimates of flow are only approximate. Data 1911 to 

1913 insufiicient for estimates of discharge. 
Cooperation. — Station maintained in cooperation with the United States Army and 

the State engineer.

FLOOD ON CAMERON CREEK AND RIO DE ARENA AUGUST 10-14, 1913. 

Rain began in the Rio de Arena and Cameron Creek basins August 
10, 1913, and continued to fall in small showers until the afternoon 
of August 14, when 2.39 inches of water fell at the United States 
Forest Service planting station above Fort Bayard and 1.07 inches 
fell at Fort Bayard. This rainfall was localized around Fort Bayard, 
as near-by precipitation records show only a moderate rainfall during 
this period. The total rainfall at the planting station from August 
10 to 12 was 2.85 inches and at Fort Bayard 1.84 inches. 

The rainfall records show that an average of 2.34 inches of rain fell 
during the period from August 10 to 14 above the gaging station on 
the drainage area of Cameron Creek west of Hurley, in the NE. | 
sec. 27, T, 18 S., R. 13 W., an amount equal to 5,490 acre-feet of 
water on the 44 square miles of drainage area above the gaging sta- 
tion. The flood reached the gaging station at 3.20 p. m. August 14 
with a discharge of 2,300 second-feet, and the stream continued to 
rise until 4.25 p. m. on the 14th, when it reached the maximum gage 



MIMBRES EIVER BASIN. 663 

height of 5.5 feet, or 5,490 sceond-feet discharge. At this point it 
began to recede and at 3 a. ra. on the 15th ceased to flow. With a 
duration of 12 hours and a mean discharge of 1,370 second-feet, this 
flood carried past the gaging station 1,360 acre-feet of water, or 25 
per cent of the rainfall on the drainage area above the station from 
August 10 to 14. This low percentage of run-ofl is attributed in 
large measure to the preceding period of drought, the general condi- 
tion of the drainage area, and the high rate of evaporation. 

At the maximum stage of the stream, or 5,490 second-feet, the 
run-off from the drainage area was 125 second-feet per square mile, 
a rate of flow that is considered very heavy, for comparison with the 
available data shows in general a lower rate of run-off for western 
streams. 

The area drained by Rio de Arena is an oblong stretch of country 
that lies west of the Cameron Creek basin and extends northward. 
The rainfall records at Silver City show less precipitation from 
August 10 to 14 than those in the Cameron Creek basin, and therefore 
the rainfall in the Rio de Arena basin is assumed to have been less 
than in the Cameron Creek basin. In the absence of rainfall data 
no attempt will be made to estimate the volume of water that fell 
on the drainage area of the Rio de Arena, above the gaging station, 
in sec. 21, T. 18 S., R. 13 W., northwest of Hurley. As measured on 
the United States Geological Survey topographic map of the Silver 
City quadrangle, that area is 16 square miles. 

The discharge at the gaging station has been estimated by means 
of the cross section and the slope of the stream, no discharge measure- 
ments being available. On August 13 from 4.55 to 6.55 p. m. a flood 
passed the gaging station. The maximum stage reached was a gage 
height of 2.20 feet, with a discharge of 105 second-feet. The mean dis- 
charge of this flood was 60 second-feet, or a run-off of 10 acre-feet. 
A second flood that occurred from 3.55 p. m. to 9.30 j). m. on August 
14 reached a maximum stage of 5.40 feet, or 1,020 second-feet at 4.20 
p. m.; the mean discharge of the second flood was 110 second-feet, or 
a run-off of 50 acre-feet for the period. 

The run-off from the drainage area during the maximum stage 
was 63.8 second-feet per square mile, or about one-half of that from 
the Cameron Creek basin. This fact confirms precipitation records 
which indicate decrease in rainfall westward. 

CLOSED BASINS BETWEEN RIO GRANDE AND PECOS RIVER. 
GENERAL FEATURES. 

As stated in the general description of the Rio Grande basin (pp. 18- 
21) there is a large area between the western headwaters of the Pecos 
and the Rio Grande proper, extending from Albuquerque into Texas, 
whose waters for the most part flow toward the interior where they 



664 



WATER RESOURCES OF RIO GRANDE BASIN, 1888-1913. 



are lost by seepage and evaporation. Within this area there are three 
streams for which fragmentary records of flow are available, Rio 
Tularosa, Rio La Luz, and Rio Fresnal. These streams all rise on 
the western slope of the Sacramento Mountains and flow westward 
until their waters sink in the sands of the great interior region. 

The upper parts of the basins of these three streams, bemg in the 
Sacramento Range, receive the heaviest precipitation, the 10-year 
mean at Cloudcroft (elevation 8,650) being 23 inches. The effect 
of altitude on precipitation is very clearly marked in this region as at 
Alamagordo, within a few miles of Cloudcroft (elevation 4,300) the 
10-year mean precipitation is less than 11 inches.

RIO LA LUZ. 



669 



RIO LA LTTZ AT LA LUZ, N. MEX. 

Location. — In the Alamo National Forest, three-fourths mile above La Luz, in sec. 

30, T. 15 S., R. 11 E., one-half mile below the mouth of Rio Fresnal, the nearest 

tributary. 
Records available. — Fragmentary records August 13, 1910, to April 4, 1913. 
Drainage area. — 74 square miles. 
Gage. — Automatic recording. From August 13 to November 23, 1910, readings were 

taken from an inclined gage referred to a different datum than is being used at 

present. The present datum has remained unchanged since November 23, 1910, 

but an automatic gage was installed July 8, 1911, in place of the incUned staff. 
Channel. — Shifting. 

Discharge measurements. — Made by wading. 
Winter flow. — No effect from ice. 

Diversions. — There are several diversions above and below this station. 
Accuracy. — Owing to the meagerness of the data, no estimates of daily or monthly 

discharge can be made. 
Cooperation. — Station was maintained in cooperation with the United States F'orest 

Service. 

Discharge measurements of Rio La Luz at La Luz, N. Mex., in 1910-1913.

RIO FRESNAL NEAR MOUNTAIN PARK, N. MEX. 

Location. — Five miles east of Mountain Park, 4 miles east of Highrolls, 1 mile below 
the Fresmal box canyon, one-fourth mile below the confluence of Rio Fresnal and 
Salado Creek, the nearest tributary, in sec. 1, T. 16 S., R. 10 E. 

Records available. — August 7, 1911, to August 23, 1912, when station was discon- 
tinued. 

Drainage area. — 44 square miles. 

Gage. — Automatic recording. From August 7 to October 28, 1911, the gage readings 
referred to the original datum are used. On November 4, 1911, a second gage was 
installed which was referred to a new datum. This datum remained unchanged 
until August 23, 1912, when the gage was washed away by a flood. 

Channel. — Shifting. 

Discharge measurements. — By wading. 

Winter flow. — No backwater from ice during winter months. 

Diversions. — There are several diversions above this station for irrigation. 

Accuracy. — On account of meager data no estimates were made in 1911 and 1912. 

Cooperation. — Station maintained in cooperation ■with the State engineer.

MISCELLANEOUS MEASUREMENTS.

MISCELLANEOUS MEASUREMENTS. 

Discharge measurements have been made at many pouits in the 
Rio Grande drainage basin other than regular stations. These 
measurements have been compiled from the annual reports of the 
United States Geological Survey and arranged in accordance with 
the general rule for presenting discharge- data. The measurements on 
the Rio Grande itself are given first, begimiing with the measurement 
nearest the source and following the stream toward its mouth. 
Measurements on tributaries are arranged in the same order and 
follow those on the main stream. 

The measurements in this list do not inciude those made during 
the seepage investigations in 1911 and 1913. 

Miscellaneous measurements in Rio Grande drainage basin.

WATER RESOURCES OF RIO GRANDE BASIN, 1888-1913. 679 

SEEPAGE. 
SCOPE OF INVESTIGATION. 

In the arid regions, where water in large quantities is used for 
irrigation and where much of the soil and the underlying strata is 
porous, the surface tributaries of a stream do not furnish all the water 
in certain sections and diversions do not account for all the losses that 
occur in other sections. This unaccounted for gain or loss in flow is 
called seepage and represents the water that percolates through the 
ground either into or away from the river. 

The underground water reaching the river — which is called return 
seepage — may have entered the ground within a comparatively short 
distance of the point at which it reaches the river or many miles 
away and in an entirely different drainage basin. If, for example, 
water is diverted to irrigate porous soil in a valley the lower end of 
which is crossed by a dike, the dike may force the percolating irriga- 
tion water near enough to the surface to permit it to reenter the river; 
or, if there is no dike across the valley, the transverse slope of the 
valley toward the river may be so great that the percolating water is 
speedily returned to the stream. An example of return seepage 
occurring at a point remote from its origin is found where water per- 
colating through the ground enters a porous stratum which leads it 
finally to the river many miles away. This water may have been 
applied to the soil for irrigation or it may have been the natural 
percolation from rainfall. 

A thorough knowledge of the geologic formation of a drainage 
basin is necessary to determine whether return seepage is water 
originally diverted for irrigation in the upper part of a drainage 
basin or from natural ground water that may have originated in an 
entirely different basin. Nor is there any certainty that conditions 
of seepage remain constant throughout the year. Thus seepage 
investigations can show little more than the actual quantities gained 
or lost in different sections of a river at the time the measurements 
are made. It is highly desirable, however, that the investigation be 
made at a time during wliich the river and its tributaries remain at 
constant stage and chiefly for this reason such work is usually carried 
on in the fall of the year or early spring, when little water is being 
diverted and the flow is nearly constant. Thus results do not show 
the actual condition during the irrigation season when the river stage 
is changing, except by assuming that seepage conditions are fairly 
constant. 

Seven separate investigations to determine the gams and losses 
from seepage in the Rio Grande have been made at mtervals since 
1900. Of these, five have covered a part of the river in Colorado,

three the canyon section between the Colorado-New Mexico line and 
the gaging station at Embudo, two between Embudo and San 
Marcial, and one between San Marcial and El Paso. 



STUDIES ON THE RIO GRANDE IN COLORADO. 

THE MEASUREMENTS. 

The investigations covering the part of the Rio Grande in Colorado 
were made by the State engineer and the results, except for the 
measurements made in 1913, were pubUshed in the biennial reports. 
As the same measuring points were not used in the various series of 
measurements it is not possible to present the results in a compara- 
tive table. For that reason the results of each investigation are 
given separately, as originally published.

Note. — During the measurements in 1913 the stage of the Rio Grande at Del Norte fell from 1.3 to 1.2 
showing a decrease in flow of approximately 70 second-feet at Del Norte. It is stated that frequent dupli- 
cate measurements showed no change in stage, so it is possible that the hydrographer kept ahead of the 
falling stage.

INTERPRETATION OF RESULTS. 

Tn order to study the effects of seepage, the river above the State 
Bridge at the entrance to the Rio Grande canyon, a few miles above 
the New Mexico line and a few miles from Lobatos, Colo., may be 
divided into three sections (1) the stretch above the Del Norte 
station, (2) that from the Del Norte gaging station to Monte Vista, 
and (3) that from Monte Vista to the State Bridge. 

Above the Del Norte gaging station little if any return irrigation 
water reaches the Rio Grande as most of the canals divert water 
below that point. Therefore any return water in all probability is 
natural undergi'ound flow from the mountains through which the 
river flows. The measurements made during the latter part of August 
1900, show a gain from the South Fork to the Del Norte bridge of 48 
second-feet, which is greater than for any other section during that 
investigation. On the other hand, the measurements made in 1903 
showed little if any return seepage above the Del Norte station but a 
steadily increasing return below that point. 

The alluvial fan built up by the Rio Grande extends from the 
entrance of the river into the San Luis Valley (near the Del Norte 
gaging station) nearly to Monte Vista, as shown by Siebenthal in his 
report on the San Luis Valley.*^ 

Across this fan, as might be expected, occur the greatest seepage 
osses above the State Bridge, although the various investigations 
have shown that these losses ai-e not constant. During the measure- 
ments in 1907, for example, no losses appeared in this section. The 
greatest losses found were 26 second-feet in September, 1908, between 
Del Norte and the head of Prairie canal, and 31 second-feet between 
the same points in October, 1913. Measurements in August, 1900, 
showed a loss of 26 second-feet in a short stretch of river above Del 
Norte, at the upper edge of the, alluvial fan. 

From Monte Vista nearly to the State Bridge the Rio Grande flows 
across the San Luis Valley, the upper part of which is extensively 
irrigated. In this section the gains from seepage far outweigh any 
losses that may occm\ In general, the various series of measurements 
show an increase of return seepage, the total below Monte Vista 
being 32 second-feet during August, 1900, 23 second-feet in Septem- 
ber, 1903, 23 second-feet in September and October, 1908, and 13 
second-feet in October, 1913. The 1907 measurements terminated 
at the mouth of the Conejos, but between that point and Monte 
Vista, the total return seepage was 67 second-feet.

THE MEASUEEMENTS. 
POINTS SELECTED. 

Three separate investigations of the seepage conditions of stretches 
of the Rio Grande in New Mexico have been made; one in March, 
1911, from the State Bridge near Lobatos to San Marcial, another 
in October, 1913, from Lobatos to El Paso, and a third in October, 
1913, from Lobatos to Embudo, at the lower end of the Rio Grande 
Canyon. The first was made by the United States Geological Survey, 
the second by the United States Geological Survey in cooperation 
with the State engineer of New Mexico, and the third by the State 
engineer of Colorado. 

LOBATOS TO SAN MARCLA-L. 

The results of measurements between Lobatos and San Marcial 
were published in Water-Supply Paper 308, from which the following

The gage-height record shows a practically uniform stage of the 
river at Lobatos during this period, but a rise at Buckman, N. Mex., 
of 0.7 foot on March 11. This rise is thought to haye been caused 
mostly by Chama River, which enters the Rio Grande a short dis- 



SEEPAGE. 685 

tance above, but a part was uiuloubtedly due to melting of snow 
and a rain which occurred in the region around Taos about March 7. 
This rise, however, preceded the measurements all the way down, 
and as the Buckman gage record shows the stage of the river to have 
been practically constant for the several days succeeding the rise 
during which measurements were made, it is thought that the condi- 
tion of the river was fairly even throughout the period. 

From the State line down to a point a few miles below Embudo 
the river flows through a box canyon which is cut in a lava forma- 
tion and ranges in depth from 50 feet at the State line to about 1,000 
feet at Embudo. In this stretch the river in accessible at only a few 
places, as little water is contributed over the surface except by Rio 
Taos and Embudo Creek. The water flowing at the heads of several 
other streams sinks soon after it reaches the sheet of lava that borders 
the river on either side and enters the river as seepage. 

Between Embudo and Buckman the canyon widens out into a 
narrow valley in which some irrigation is carried on, and the river 
spreads out over a sandy bed and among islands. 

From Buckman the river flows in a comparatively narrow chaimel 
through White Rocks Canyon to Cochiti. At Cochiti the valley 
opens again into a flat sandy plain, and thence practically to San 
Marcial the river spreads out over a broad bed and among sand bars. 
Along this stretch considerable irrigation is practiced. 

At the Lobatos, the mouth of the Rio Hondo, San Juan, Buckman, 
Cochiti, and San Marcial, very good measurements of the Rio Grande 
were obtained. Conditions at the other measured sections were 
unfavorable and results are only fair. 

It should be noted that the river loses little, if any, water by diver- 
sion or otherwise above Embudo, and that below Embudo more or 
less water is being div^erted for irrigation; also, that in the lower 
stretch considerable loss from evaporation results from the spreading 
of the river over so much area and the openness of the valley. 

LOBATOS TO EL PASO. 

A special investigation of gams and losses in the Rio Grande from 
seepage between the State bridge near Lobatos, Colo., and El Paso, 
Tex., was made October 20 to 30, 1913, under the direction of Glenn 
A. Gray, district engineer in charge of the Santa Fe district. The 
stream was divided into four sections, a hydrographer being detailed 
to each section. The discharge was measured at various intervals 
along the main stream, at the mouth of each tributary, and at the 
headgate of each diversion. 

Automatic gages are maintained on the Rio Grande at the State 
bridge near Lobatos, Colo., at Embudo, N. Mex., Buckman, N. Mex., 



686 



WATER RESOURCES OF RIO GRANDE BASIN, 1888-1913. 



on the Cliama River at its mouth near Chamita, N. Mex., and on the 
Rio Puerco at its mouth. Staff gages, read twice daily, are main- 
tained on the Rio Grande at San Marcial, N. Mex., and El Paso, 
Tex., and on the Rio Hondo at its mouth. These gages showed the 
stream to be falling gradually during the last of October, with no 
floods to interfere with the investigation. 

From available maps, automatic gage records, and discharge meas- 
urements it was estimated that 10 days would be required for water 
to flow from the State bridge to El Paso, Tex. By the aid of the 
automatic gage charts, the estimated rate of flow, and the discharge 
measurements the entire seepage data were corrected to represent 
measurements of the same water passing different sections. 

These data represent natural conditions as they were found above 
Selden, N. Mex. Below this point the flow is controlled by the Leas- 
burg diversion dam, which irrigates a large area. It was found ex- 
tremely difficult to draw conclusions from observations below Elephant 
Butte, and in view of the fact that the Elephant Butte dam will soon 
control the flow to the New Mexico-Texas State line, more attention 
was given to that part of the stream above this point.

engineer of Colorado made an investigation from the State Bridge, 
near Lobatos, Colo., to Embudo, N. Mex. The following table has

INTERPRETATION OF RESULTS. 

To make the results of the various measurements directly com- 
parable, an allowance must be made for changes in the flow of Rio 
Grande, as determined in the first and third series of measurements. 
In the first investigation the flow was measured at the head of the 
box canyon 1^ miles below Questa and about 8 miles above the mouth, 
and as there are no intervening tributaries, the discharge at the mouth 
was assumed to be the same; in the second series of measurements, 
the discharge was determined both at the head of the canyon and at 
the mouth, and it was found that the flow increased in the canyon from 
28.1 to 67.1 second-feet, a gain of 39 second-feet. Therefore it is 
evident that the discharge for Rio Grande, as determined in the first 
investigation, did not represent the entire flow entering the Rio 
Grande. It is impossible to state what the increase was in March, 
1911, when the first seepage measurements were made, but as under- 
flow is much more constant than surface run-off, the results wiU be 
more nearly correct if the increase of 39 second-feet is apphed to the 
discharge of the Rio Colorado, making it 69 second-feet instead of 
30 second-feet, as given originally. This \vill reduce the seepage gain 
between the Lobatos station and Dunn's bridge from 134 to 95 second- 
feet, and reduce all subsequent values in the last column by the same 
amount. 

In the third series of investigations tlie measurement was made 4 
miles below Questa, and the results obtained were practically the 
same as those obtained in the second series at the head of the box 
canyon. Therefore it is evident that this discharge of 30 second-feet 
should be increased by 39 second-feet to show the flow of Rio Colorado 
at its mouth — especially as the second and third series were made 



SEEPAGE. * 689 

within a few days of each other. Thus the flow of Rio Colorado 
entering the Rio Grande was 63 second-feet, and the seepage gain 
between Lobatos and Dunn's bridge 88 second-feet instead of 127 
second-feet, as given in the preceding table. This change also reduces 
the total seepage gain at Embudo from 130 to 91 second-feet. A 
smaller increase, amounting to 4.3 second-feet, was found on Rio Taps 
between Los Cordovas and the mouth, but this correction, being 
relatively unimportant, has not been applied to the first and third 
series of measurements. 

To study in some detail the seepage conditions along the Rio 
Grande in New Mexico, the river may be divided into three sections: 
(1) Rio Grande canyon extending from the State Bridge near Lobatos, 
Colo., to Embudo, N. Mex.; (2) Espanola Valley and White Rocks 
Canyon, extending from Embudo to Pena Blanca, and (3) the section 
from Pena Blanca to El Paso. 

An attempt was made to compare by sections the results of the 
various seepage investigations but, except for the part of the Rio 
Grande canyon above Dunn's bridge, the results are so discrepant 
that the attempt was abandoned, and instead, the general effects of 
seepage in different parts of the river is discussed in connection with 
the measurements made in 1913. 

Except for a few small ditches below Glenwoody, there are no 
diversions for irrigation in the Rio Grande Canyon and, therefore, 
any return seepage does not come from near-by irrigation water 
diverted from the Rio Grande, as it probably does in San Luis Valley, 
but must come from a source more or less remote and may be either 
return irrigation water or natural underground water. The investi- 
gations in the upper part of this section all show a comparatively 
large return seepage. The measurements made in 1911 determined 
this to be 95 second-feet, whereas the two separate investigations in 
October, 1913, found it to amount to 140 and 88 second-feet, respec- 
tively. There is httle seepage in the lower section of the canyon. 

From Embudo to the mouth of the Chama near San Juan there was 
no return seepage and seepage losses amounted to 74 second-feet. 
These losses are accounted for by the porous soil over which the river 
flows in Espanola Valley. From the mouth of the Chama to the 
lower end of White Rocks canyon, near Pena Blanca, return seepage 
amounted to 104 second-feet, half of which occurred in the lower end 
of Espanola VaUey in the 4 miles between San Juan and Espanola. 

Measurements made in 1913 showed that practically no return 
seepage reached the river below White Rocks Canyon, and that 
seepage losses were large. From Pena Blanca to Bernalillo there 
was little seepage loss, in spite of the fact that tliis section is irri- 

41823°— WSP 358—15 44 



690 WATER EESOUECES OP RIO GRANDE BASUST, 1888-1913. 

gated extensively, and had been irrigated within a few weeks of the 
measurements. The absence of return seepage is probably due to the 
very porous soil in the river bed itself and to losses by evaporation of 
the water diverted for irrigation. This same condition is more 
marked in the lower part of the Albuquerque Valley and the Belen 
Valley in the section extending from Bernalillo to San Acacia near 
the mouth of the Arroyo Salado. The most rapid state of seepage 
loss in the New Mexico portion of the Rio Grande occurred between 
Bernahllo and Albuquerque, where, in a distance of 20 miles, the 
loss amounted to 100 second-feet, in a section extensively irrigated 
both during and prior to the investigation.^ Below Albuquerque the 
seepage loss is less, being practically nothing as far as Las Lunas, but 
from that point to the lower end of the Engle Reservoir site at 
Elephant Butte, the investigations showed seepage loss aggregating 
254 second-feet in 130 miles. Between Elephant Butte and El Paso 
the seepage loss is much smaller — only 59 second-feet in 116 miles. 

STUDIES ON CHAMA HIVER. 

In addition to the seepage investigations on the Rio Grande itself, 
an investigation has been made of the seepage losses and gains in 
Chama River from Chama to its mouth. 

The gains and losses from seepage were investigated along Chama 
River from Chama, N. Mex., to the mouth of the stream by measuring 
the main stream, tributaries, and diversions at various points. The 
investigation was begun at Chama, N. Mex., October 28, 1 9 13 , by Frank 
O'Brien, junior engineer. United States Geological Survey, who car- 
ried the work to a point 46 miles south by river, or the mouth of the 
Gallinas River. From this point to the mouth of the Chama the work 
was done by John E. Powers, hydrographer for the State of New 
Mexico. Other investigations have been planned for the Chama River 
basin as it is beheved that stage of stream, preceding climatologic 
conditions and seasonal elements, are influential factors in regulating 
seepage in a basin. 

Automatic gages are being maintained on Chama River just 
above the confluence with the Rio Grande, El Vado, and Park View, 
and a staff gage is read twice daily at Chama. An automatic gage 
is also being maintained on Brazos River at the mouth of the Bos 
Canyon, so that the flow of the largest tributary of Chama River can 
be determined. 

During the period covered by this investigation the gages above 
El Vado showed some diurnal change caused by the melting snows. 
These changes in stage did not affect the flow at El Vado or that 

1 It may be noted that during the measurements in March, 1911, return seepage amounting to 185 second 
feet was found in this section. The flood which occurred in the Chama during the latter measurement 
made the results below the mouth of that stream uncertain. 



SEEPAGE. 691 

part of the stream below this point. The stage remained constant 
during the period from October 28 to November 3. Heavy rains 
aromid Abiquiii, Espanola, and north of Chamita caused the Chama, 
above the mouth of Ojo CaUente, to rise slightly, Ojo Caliente to 
carry 39 second-feet of water, and the lower Chama to rise about 1 
foot. 

The data taken along the stream were corrected for time interval 
by means of the gages along the Chama and the velocities as obtained 
from the various discharge measurements. In this way it has been 
estimated that water that passed Chama the morning of October 29 
reached the Rio Grande the morning of November 1. 

Chama River flows through a fertile valley from Choma to a point 
a short distance above the mouth of Nutritus Creek, where it boxes 
up and passes through a canyon to El Vado Valley. At the end of 
El Vado Valley, which is about 4 miles long, the stream passes 
through the Canyon de Chama, opening into Gallinas Valley. From 
Gallinas Valley it flows through a canyon above Abiquiu, whence it 
passes through a valley that joins the Espanola Valley of the Rio 
Grande. The topography along some sections of the Chama is so 
rough that it is exceedingly difficult to carry on an investigation of 
this kind. 

The following tables show the results of this work as compiled from 
the discharge measurements taken in the Chama basin on the main 
stream, tributaries, and irrigation ditches carrying water; also the 
record of daily gage heights taken from the various gages in the basin 
for the period of investigation :

The measurements show that the surface contributions and diver- 
sions are at a minimum, there being 1 . 1 second-feet of water diverted 
and 28.7 second-feet contributed through the part of the stream 
investigated. It should be noted that 21 per cent of the flow is lost 
by seepage between Chama and Park View, and 42 per cent returns 
through seepage between Park View and the mouth of Nutritus Creek. 
In the canyon below the mouth of Nutritus Creek there is a gain of 
17 per cent, in El Vado VaUey a loss of 31 per cent, in Canyon de 
Chama a gain of 13 per cent, in GaUinas VaUey a gain of 64 per cent, 
in Abiquiu Canyon neither gain nor loss, and in Abiquiu VaUey a loss 
of 29 per cent; the net result is a gain of 55 per cent between Chama 
and the mouth of the stream. 



EVAPORATION. 

THEORY OF EVAPORATION. 

The waters of the Rio Grande and its tributaries are already so 
fully utilized that any increase in development must come chiefly 
through storage of the flood waters. Whenever water is stored, and 
especially in a climate so hot and dry as that characterizing the 
greater part of the Rio Grande basin, it causes serious losses. 

The following brief discussion, based on "The general theory of 
evaporation" given in the Weather Bureau's Manual for Observers, 
is presented to show the factors that influence the rate of evapora- 
tion, in order that the magnitude of the phenomenon for any par- 
ticular locality may be better understood. 

From the surface of any sheet of water when the air rests upon it 
without motion, as in a calm, a series of vapor-pressure tubes extend 
upward, gradually spreading out into a sheaf like the magnetic lines 
surrounding the poles of a magnet. The vapor pressure at the water 
surface is a maximum, depending on the temperature of the water 



EVAPORATION . 695 

surface. The pressure at any point in the tube varies inversely with 
its distance from the water surface and is a minimum at the dew 
point of the air. In other words, there is a vapor bhinket over the 
water surface caused by the particles of water passing from the water 
surface into the air. This blanket is densest at the water surface 
and becomes thinner as the distance above the water surface increases. 
The total depth or tliickness of the vapor blanket is determined by 
the relation between the vapor pressure at the water surface and the 
vapor pressure of the dew point of the air, Wlien these two are 
equal, there is little if any evaporation. When the difference between 
the two pressures is greatest (the pressure at the water surface being 
the greater) evaporation takes place at a maximum rate. When the 
vapor pressure of the air increases beyond the dew point there is a 
negative flow of vapor in the form of rain (or snow). 

From the foregoing it is evident that two very important factors 
influencing evaporation are the temperatures of the water and of the 
air. It may be noted that the drier the air the less its vapor pressure 
and, therefore, the greater the evaporation. Thus both temperature 
and humidity (or amount of moisture) of the air influence evaporation. 

Another most important factor is the velocity of the wind across 
the water surface. The wind blows away the densest portion of the 
vapor blanket that is in direct contact with the water surface, and in 
its place brings in drier air whose vapor pressure is much less. This 
greater difference in vapor pressure between the water surface and 
the air in contact with it immediately induces a greater rate of flow 
along the vapor tubes — just as the amount of water delivered by a 
pump against a pressure head is increased as soon as the pressure 
head is reduced. 

METHODS OF MEASUREMENT. 

The most direct way to determine evaporation is actually to 
measure the loss of water in a pan. 

The United States Weather Bureau, which carried on extensive 
experiments with evaporation pans placed in various surroundings, 
found that pans placed in the ground absorbed so much heat from 
the soil that the temperature of the water was greater than that in 
near-by ponds and reservoirs, and therefore the evaporation recorded 
was greater than simultaneous records from pans floating in the water; 
also, that pans placed at different heights above the water surface 
showed different results, depending on their relative positions in the 
vapor blanket. In problems involving storage the actual evapora- 
tion from the water surface should be determmed, and, as evaporation 
is very sensitive to atmospheric conditions within an inch or two of 
the water surface, the most desirable position in which to place the 
measurmg pan is to float it on the water itself. Unfortunately, in 
bodies of water exposed to high winds it is impossible to prevent the 



696 WATER EESOUECES OP RIO GRANDE BASIN, 1888-1913. 

waves from slopping into the pan and vitiating the results, and there- 
fore it is usually necessary to select a relatively sheltered point in the 
pond or reservoir rather than one which is exposed to the effect of 
the average wind. The error introduced by this selection of location 
is within the limits of error allowable in solving hydrauhc problems 
dealing with storage and use of water. 

As more evaporation records are taken from ground pans than 
from floating pans, the following experiments are cited to show the 
errors that may be introduced by using the ground-pan records. 

At Hermiston, Oreg., and at Granite Reef, Ariz., the Weather 
Bureau found that evaporation from the pans set in the ground was 
greater than that from pans of the same size floating in water. The 
ground-pan record at Hermiston shows a total annual evaporation 
of 97.29 inches for the floating pan, 68.05 inches, or an excess of 43 
per cent more than the water record. At Granite Reef the ground 
pan gave 115.18 inches and the floating pan 97.74 inches* an excess 
of 18 per cent. 

On the other hand, Prof. L. G. Carpenter, in his experiments at 
Fort Collins, Colo., found the temperature of the water in the ground 
pan to be less than that in near-by lakes and reservoirs, and increased 
his annual results from 46.3 inches to 59.5 inches, an increase of 28 
per cent, to obtain the evaporation from reservoir surfaces. A like 
excess of floating-pan records over those for ground pans was found 
by Desmond Fitzgerald near Croton Reservoir, New York. 

It is evident from these experiments that records from pans set in 
the ground do not give the same results as floating pans, nor is it 
known definitely whether the ground-pan rates are too large or too 
small when applied to reservoir surfaces. Though the records from 
pans floating on the water surfaces are open to criticism, they 
approach much nearer true conditions for evaporation from large 
water surfaces than do the records from pans set in the ground. 

RECORDS OF EVAPORATION. 

So far as known, there are but three points in the Rio Grande 
drainage basin where evaporation records from pans floating in the 
water have been taken — at Fort Bliss near El Paso, Tex., at Lake 
Avalon near Carlsbad, N. Mex., and at Santa Fe, N. Mex. Records 
from pans set in the ground have been kept at several points. 

FORT BLISS. 

From 1889 to 1893 the United States Geological Survey kept an 
evaporation pan, 3 feet square and 10 inches deep, in the Rio Grande 
at Fort Bhss near El Paso. Owing to the difficulty of obtaining 
observations the results are fragmentary. The monthly summaries 
are given in the following table:

for each month. 

LAKE AVALON. 

Records of evaporation during 1909-10 were obtained by the 
United States Weather Bureau from a pan 4 feet in diameter floating 
on the surface of Lake Avalon a few miles north of Carlsbad. The 
following table shows the monthly summaries determined from these 
records :

As the records at both Fort BUss and Lake Avalon are fragmen- 
tary, it is due chiefly to chance that the mean annual evaporation, as 
showm by the two, agree so closely. 

SANTA FE. 

Since May, 1913, records of evaporation have been obtained by 
the United States Geological Survey from a pan 3 feet square float- 
ing m an irrigation reservoir on Jones's ranch, three-fourths mile 
west of Santa Fe. The monthly summaries of evaporation are given 
in the followuig table:

WATER EESOUECES OF EIO GRANDE BASIN, 1888-1913. 



The foregoing records are too brief to give conclusive evidence 
regarding evaporation in the Rio Grande Basin. It should be borne 
in mind, however, that the annual evaporation varies less than ram- 
fall or run-off, and therefore long-time records are not so essential. 

No records of evaporation from floating pans in the Colorado part 
of the basin, which includes the San Luis Valley, are available, but 
an approximate estimate can be made for San Luis Valley from the 
Santa Fe records. San Luis Valley is 600 to 1,000 feet higher than 
Santa Fe and is surrounded by mountains. The higher altitude 
tends to reduce the mean temperature and thus reduce evaporation. 
The effect of the lower temperature is at least partly offset by the 
greater altitude, which tends to increase evaporation by reducing 
atmospheric pressure. As these factors are more or less compensat- 
ing, it is believed that evaporation in the San Luis Valley will not 
differ greatly from that at Santa Fe. 

HECOEDS FROM PANS SET IN THE GROUND. 



Although records of evaporation as determined from pans set in 
the ground are Hable to large errors and must be used with caution, 
the following table showing the annual evaporation is presented to 
show the variation at different points and under different conditions :

WATER RESOURCES OF RIO GRANDE BASIN, 1888-1913. 699 

SEDIMENTATION. 

SILT IN RIO GRANDE WATER. 

The Rio Grand© is ono of the most heavily silt-laden streams in the 
United States, and any contemplated diversion or storage of its waters 
must take account of the sediment. In its u])per stretch the river, 
above Del Norte, is a clear mountain stream, flowing in a channel of 
bowldei-s and gravel and receiving tributaries of a similar character, 
but as it flows through the San Luis Valley its bed gradually becomes 
more sandy, and a small amount of suspended matter appears, but the 
river does not carry any considerable quantity of sediment until it 
receives the waters of Chama River, which is the first silt-laden stream 
to enter it. Below the mouth of the Chama the sediment increases, 
the Jemez River and Galisteo Creek frequently bringing down silt. 
The principal sources of sediment, however, are the Puerco and the 
Salado— torrential streams of great declivity — which in flood bring 
down large quantities of mud. For weeks after one of these floods 
the water of the main river will be loaded witli silt as far down as the 
mouth of the Conchos. Even the snow waters in the spring of the 
year, which are clear in the upper portion of the river, accumulate 
considerable silt in the alluvial valleys — silt from caving banks and 
the remains of the Puerco's summer floods. This muddy water is 
diluted by the clearer waters of the Conchos, Pecos, and Devils rivers, 
and the springs in the canyon. 

W. W. Follett, in his report on ''Silt in the Rio Grande," separates 
the Rio Grande, as regards sediment, into three divisions. From its 
source to Albuquerque it is clear, except in its lower portion, where it 
sometimes carries silt from the Chama and Jemez Rivers and Galisteo 
Creek; from Albuquerque to the mouth of the Conchos the water is 
muddy and sometimes saturated with silt. Below the Conchos the 
Rio Grande is a silt-bearing stream, but the average percentage of 
silt is much less than in the middle section.

Measurements, made at El Paso and San Marcial for a number of 
years, to determine the amount of sediment carried by the Rio Grande 
show that no definite relation exists between the discharge of the river 
and the silt carried. Furthermore, the variation in total volume of 
silt carried each year is so much greater than the variation in the total 
discharge that prediction of sediment in future years is more uncertain 
than that of the discharge. 

The first recorded determination of sediment in the Rio Grande was 
made at El Paso by the United States Geological Survey m 1889 and 
1890.^ The method followed was to collect a sample from the flowing

water in a horizontal cylinder having vertical sliding doors at each end. 
Samples were taken at about half a foot below the surface for the top 
sample, and the same distance above the bottom for the bottom sample. 
These samples were then placed in covered jars and allowed to settle 
for three or four days. At the end of that time the clear water was 
carefully drawn off with a glass siphon and the sediment washed out 
upon filter paper by means of a jet of clear water. The filter papers 
were previously dried and weighed, and after receiving the sediment, 
were again dried for 24 hours and carefully weighed, due precautions 
bemg taken against increase of weight by absorption of moisture 
from the air. Each sample weighed was made up of water taken from 
the top and bottom of the section, sections being chosen in the center 
of the stream, and from 30 to 60 feet from each shore (width of section 
220 to 230 feet) to determine the average conditions. The amount of 
silt in the water was expressed as percentage by weight, no attempt 
being made to determine the percentage by volume. 

From May, 1897, to December, 1904, samples of water near El Paso 
were taken under the direction of the International Water Boundary 
Commission and furnished to Prof. J. C. Nagle of the Agricultural and 
Mechanical College of Texas, who determined the percentage of sedi- 
ment by volume and by weight. 

Most of these samples were taken in a quart bottle that was lowered 
slowly from the surface to the bottom of the river, and then after a 
slight pause drawn slowly to the top. The movement was so timed 
that the bottle was filled about the time it reached the surface. The 
percentage of silt by volume was determined by pouring the samples 
into calibrated glass tubes and allowing them to settle for a week, 
when the depth of the sediment at the bottom was measured. The 
percentage by weight was determined by taking a given quantity of 
the well-shaken sample and filtering it through a Gooch crucible until 
the effluent was clear, then drying the sediment and weighing it. 
Beginning January 1, 1905, and extending to May 31, 1910, samples 
were taken more frequently at El Paso, and the silt percentage, by 
weight, of those taken from January 8, 1905, to April 30, 1908, was 
determined at the Berkeley, Cal., laboratory of the United States 
Reclamation Service. After that date the determinations were made 
by Mr. Arthur W. Houck in his El Paso laboratory. The method 
used by the Reclamation Service is not stated. Mr. Houck has deter- 
mined his percentage of silt by weighing carefully the whole sample, 
then running it through filter paper, drying out, and weighing the 
residual. The percentage is then obtained from the two weights. 

The International Water Commission has obtained for the Recla- 
mation Service semiweekly samples of the Rio Grande water at 
San Marcial from May, 1905, to the present time, and with the ex- 
ception of the work done by Prof. Nagle, no attempt has been made 



SEDIMENTATION. 701 

to determine from the samples themselves the percentage of silt by 
volume for silt compacted in a reservoir or canal. The volumetric 
results obtained by Prof. Nagle, being three or four times as largo as 
those by weight, dry, have been thought by the Government engi- 
neers making the silt determination to bear no relation to actual 
conditions in reservoirs and canals, and have been discarded. 

RELATION BETWEEN WEIGHT AND VOLUME OF SILT. 

To determine the proper relation between the weight and volume 
of silt compacted in a reservoir or canal, a special investigation was 
made in 1904. As the value of the silt records depends largely upon 
the determination of this relation, the following discussion is quoted 
from FoUett's report (Silt in the Kio Grande) : 

In 1904 the Reclamation Service began a careful study of the Rio Grande conditions, 
preparatory to the development of the Rio Grande project. Mr. B. M. Hall was the 
supervising engineer in charge and he discussed with the wi'iter the silt problem in all 
its phases. The question of paramount importance was the space which the silt 
would occupy in the proposed reservoir. It was evident that the per cent by weight, 
dry, was too small, as the silt Avould never be dry in the bottom of a reservoir and as it 
is a well-known fact that clay or clayey earth will swell when wet and as all Rio Grande 
silt contains a large percentage of clay. This statement is based on the assumption 
that the specific graAdty of the dry silt is the same as that of water. While, at first 
sight this seems improbable, it appearing that its weight would be more than that of 
water, the investigators knew that the Rio Grande silt was extremely Hght. Others, 
* * * have, since 1904, assumed that a cubic foot dry weighs 85 pounds, but there is 
no statement given of an actual weighing of a fixed quantity of dry silt, no more than 
there was in 1890, when it was assumed to weigh 100 poimds per cubic foot. It was not 
the specific gravity of dry silt which was wanted anyway. It cut no figure whatever in 
the problem. The unit which was desired was the amount of silt which would fill a 
cubic foot of space when fully settled and when compressed by the overlying load of 
water, and its relation to the per cent by weight of dry silt to the water which carried it. 

It was evident that the per cent by bulk, obtained from test tubes, would be too 
large for the desired unit because there was no weight on the silt in the tube to comj^act 
it, as there would be in a reservoir, and because the mud would stick to the glass and 
BO not settle. 

Something more than guess work was wanted. It did not seem proper to us to foimd 
all our silt calculations on an assumed bulk for it which was, as it were, simply pulled 
out of the ail'. The desire was to approximate as closely as possible to the conditions 
which would be found in the bottom of a reservoir. After considering various schemes, 
to all of which there seemed to be vaUd objections, it was finally decided to seek a mud 
bar in the river where the water had been comparatively still and which had shrunk 
enough to show material cracks, and to cut from this bar a 3-inch cube, have it 
dried out and weighed and to abide by the result, whatever it was. The idea was that 
a bar should be chosen which had shnmken enough to make up for the compression 
which the silt in the bottom of a reservoir" would undergo from the weight of the water 
over it. Of course, the necessary amount of shrinkage could not be told exactly, but 
it was thought that a fairly good guess could be made. 

On Jime 29, 1904, Mr. Hall and the writer carefully cut a 3-inch cube of silt free from 
gravel out of a sediment bar just above the Mexican dam at El Paso. The bar showed 
signs of material shrinkage since the water had receded, there being large cracks in it, so 
that it was decided that the piece cut out, having already shrunken considerably from

exposure to the air, would fairly meet the prescribed requirements. This sample was 
taken to Mr. Arthur W. Houck, who had had some 15 years' experience in analytical 
chemical work. He dried it out at a temperature high enough to evaporate the water 
but not so high as to volatilize any of its substance, and then weighed the residual. 
He found its dry weight to be 5,789 grains or 0.827 pound (7,000 grains to the pound). 
There would be 64 of these cubes in a cubic foot, or a cubic foot of wet silt in the bar 
from which this was taken would, when dried out, weigh 53 pounds or 85 per cent as 
much as a cubic foot of water (the latter weighing 62.4 pounds). 

It has been assumed that the above experiment fairly determined the weight of 
reservoir silt and that all silt determinations should be divided by 0.85 in order to 
obtain the actual final volume of the silt. 

It may be objected that the results involved are too important to make them depend 
upon one single observation, as was done in this case. In reply it should be stated that 
the conditions imder which the silt will settle in a reservoir are not well known and 
that there are enough other indeterminate factors in the problem to render it probable 
that this one sample, deliberately and intelligently chosen by two trained men who 
were fully conversant with all the conditions confronting them and who were careful 
in their selection of the sample, would give a result fully as good as might come from 
the mean of many samples taken with less care. Moreover, the result appeared to be 
reasonable. 

It should be stated that the Rio Grande silt contains no sand coarse enough to be 
perceptible. It is composed of finely dessicated and almost impalpable clay and allu- 
vium and it settles slowly. Therefore, it is not proper to compare its density when 
settled with that of silt, which has much sand in it. Of course, the suspended silt, 
when settling in the river, frequently becomes mixed with the sand, which is moving 
on the bottom of the river, and hence mud bars frequently show some sand. This 
sand was not carried in suspension, however. 

RECORDS OF SILT DETERMINATION AT EL PASO AND SAN 

MARCIAL. 

The determinations of silt made by the Geological Survey in 1889- 
90 were by weight, and in estimating the total amount of silt passing 
El Paso the acre-feet (assuming the silt to weigh the same as water) 
carried each month was obtained by averaging the various percentages 
determined during the month. As this method did not take into 
account the great variation in discharge to which the percentages ap- 
plied, its results were less accurate than those obtained by determin- . 
ing the actual silt for each day from the different percentages and 
taking the sum of these as the total silt for the month and computing 
the mean percentage for the month by dividing the silt by the dis- 
charge in acre-feet — the method used by Mr. Follett in his report. 
To make the records comparable with the later records at El Paso 
and San Marcial, the mean monthly percentages have been divided 
by 0.85 on the assumption that the compacted silt will weigh 53 
pounds per cubic foot. The following table shows the monthly dis- 
charge in acre-feet of the Rio Grande near El Paso during the period 
covered by the Geological Survey silt determination, the mean 
monthly silt percentages, and the total silt in acre-feet carried by the 
river each month:

TOTAL SILT CARIIIED IN SUSPENSION PAST SAN MARCIAL. 



Although determinations of silt and records of discharge are 
available at both San Marcial and El Paso, the Eagle reservoir of the 
Reclamation Service, located 40 miles below San Marcial, has made 
the computations of the total silt passing that point of greater 
importance. For that reason the estimates for San Marcial have 
been made by Mr. Follett. For the estimates prior to 1905, when 
only the El Paso determinations were available, monthly percentages 
of silt by volume were made from the El Paso records, modified some- 
what by an intimate knowledge of the river between the two points. 
Subsequent study indicated that not enough changes were made in 
the El Paso table to fit the conditions at San Marcial — that the per- 
centages used for storm-water montlis were usually too small and that 
used for usual winter flow was too lai^e. It is beheved, however, 
that they will balance fairly well. Tlie following table shows the 
monthly discharge in acre-feet, percentage of silt by weight, and total 
silt in acre-feet, passing San Marcial from 1897 to 1912, inclusive:

SEDIMENT MOVING ON BOTTOM OF RIVER. 

The foregoing records show only the sediment carried in suspen- 
sion. In regard to the sediment moving on the bottom of the river, 
Mr. Follett states : 

There is also a large amount of sediment which is rolled along the bottom. No 
method has yet been devised of measuring this moving sediment. That its amount 
is large is shown indirectly by many phenomena. How large it is the writer is unable 
to say with any degree of confidence. That it may amount to 25 per cent of the silt 
carried in suspension he believes possible. The amount will vary greatly with 
different streams, the factors affecting it being the weight and fineness of the sedi- 
ment, the declivity of the stream's bed, and the number and abruptness of variations 
in flow. It is unfortunate that it can not be measured and studied as can the silt in 
suspension. It adds an indeterminate factor to the problem which is troublesomely 
large. The only way its amount can ever be arrived at will be by the measuring, for 
a long series of years, of the deposit in some existing reservoir, together with the delta 
at its head, while silt determinations are kept up. In this way a result may finally 
be deduced for one stream, but the question of its applicability to other streams will 
be an open one. 

SEDIMENTATION IN PECOS RIVER.' 

The silt in the upper Pecos Valley consists of nothing more than 
the material ground away by the mountain torrents, and soon settles, 
often before reaching the main channel. Low^er down on the river, 



' Taken chiefly from U. S. Reel. Service Third Ann. Rept. 



716 WATEE EESOUECES OF EIO GEANDE BASIN, 1888-1913. 

where the course is thi'ough alluvial soil, more silt is gathered until 
at the McMillan reservoir the water is heavily charged. 

In 1904 the United States Reclamation Service made borings in 
the bottom of Lake McMillan reservoir, which was then dry, to 
determine the amount of silt deposited in its 10 years of service. 
Ordinary screw post-hole diggers supphed with extension shanks 
were used to make the borings, and the natural surface beneath the 
silt was determined by the change of color in the material and also 
by the particles of vegetable matter found in most places where the 
natural surface was reached. 

At the time of the borings the reservoir had accumulated 12,232 
acre-feet of silt, and as the capacity of the reservoir was then 16,500 
acre-feet, the original capacity was 28,732 acre-feet — a decrease in 
capacity of 42 per cent in 10 years. In addition to the silt deposited 
in the reservoir, there was a considerable deposit above the highest 
storage contour. A few random borings taken at a considerable 
distance above the contour showed the depth of silt to be greater 
than at any point within the storage area. This was due to the fact 
that when the river flood met the still water in the reservoir the 
velocity was checked and the heavier sediment deposited. The 
investigations were not sufficiently extensive to indicate the amount 
of silt deposited outside the storage area.
